This case report describes the use of platelet-rich fibrin (PRF) and immediate dental implants to treat a deficient anterior ridge. Three deciduous teeth were extracted atraumatically while preserving the alveolar ridge. Platelet-rich fibrin was prepared from the patient's blood and used to coat the implant surfaces after placement. The PRF aims to enhance osseointegration and bone formation. Clinical and radiographic evaluation after 3 months found substantial bone volume increase and density, indicating PRF and immediate implants can successfully treat anterior ridge deficiencies.

This study measured and compared the stress transmitted to implants from different attachments for mandibular implant overdentures. An edentulous mandibular model with implants in the canine regions was fabricated. Strain gauges attached to the implants measured stress under vertical pressure applied to the denture. A locator attachment transferred more stress to the working side implant than a bar/clip attachment. Stress on implants decreased as the denture base length was reduced. The bar/clip attachment distributed stress more evenly between working and non-working side implants.
Soft denture liners provide cushioning effects for patients with resorbed ridges and thin mucosa, improving masticatory function. This article describes a new indirect method for applying silicone soft-lined dentures using a photo-activated spacer to control the thickness and location of the soft lining material. The denture base material and soft lining material are simultaneously polymerized. This technique allows for dentures with reliably controlled soft lining material on the intaglio surface and hard-resin marginal base. The method was used successfully in 5 patients who experienced reduced pain and improved mastication.
loading protocols in dental implants about indications and contraindications of conventional , immediate,progressive and delayed loading of dental implants
This document discusses immediate loading of dental implants. It defines immediate loading as loading an implant with a restoration within 2 weeks of placement. Immediate loading has benefits like eliminating a second surgery and allowing immediate function. However, it risks overloading the implant interface during bone healing. Factors that reduce this risk include increasing the implant surface area, decreasing occlusal forces, and using bone-friendly surfaces like hydroxyapatite. The document describes procedures for immediate loading in fully and partially edentulous patients, including using a provisional restoration made on the day of surgery or at a follow-up appointment. A soft diet is recommended during initial healing from immediate loading.
This document discusses occlusal schemes for implants, known as implant protective occlusion (IPO). IPO aims to reduce stress at the implant-bone interface through 14 considerations including eliminating premature contacts, positioning occlusal contacts over implant bodies, reducing cantilever lengths, and decreasing crown heights. The goals of IPO are to reduce force magnification, improve force direction, and increase the implant support area to promote implant longevity and success.
Journal Club Presentation on Overlay Removable Partial DentureNeerajaMenon4
Overlay removable partial dentures (ORPDs), a subset of overdentures, are often referred to as an RPD that has part of their components covering the occlusal surface of the abutment teeth to restore them into a functional occlusion
There are several protocols for loading dental implants after surgery based on bone density and healing time requirements. Protocols include Brånemark's loading protocol, progressive loading, and immediate/early loading. The density of the bone where the implant is placed determines the appropriate loading protocol, as less dense bone requires more healing time before loading to allow for sufficient bone mineralization and strength. Progressive loading gradually increases stress on the implant over time to allow the bone to adapt, reducing risks of failure. It is particularly important for lower density bone which is weaker.

1. A tooth supported overdenture is a removable partial or complete denture that covers and receives support from one or more remaining natural teeth or dental implants.
2. It provides advantages like ridge preservation, improved retention, stability and support compared to conventional complete dentures.
3. Tooth supported overdentures can be classified based on the type of abutment preparation (coping vs non-coping) and the timing of placement (immediate, interim or definitive).
Platform switching involves using a smaller diameter abutment on a larger diameter implant. This shifts the implant-abutment junction inward and away from the crestal bone. According to the document, platform switching reduces crestal bone loss in the following ways: 1) It shifts the inflammatory cell infiltrate inward, decreasing its effect on the crestal bone. 2) It maintains the biological width between the implant and bone. 3) It decreases stress levels in the peri-implant bone by shifting the stress concentration area away from the bone-implant interface. The document discusses the concept, history, advantages, and limitations of platform switching.

Fabrication of functional complete dentures for edentulous patients who have undergone hemimandibulectomy is a very arduous and demanding endeavor.
The most challenging situation encountered during this procedure is the deviation of the mandible to the resected side. The deviation of the mandible to the resected side is directly proportional to the loss of tissues in the area hemi-mandibulectomy has been performed.
In cases with Cantor and Curtis classes II, III, IV, and V, guide flange prosthesis would be a treatment modality. For guide flange prosthesis to be effective, the sufficient number of posterior teeth that are periodontally sound should be present in the opposite arch.
In patients where reconstruction is not done after resection of the mandible, scar tissue formation occurs over a period of time that stiffens the tissues and worsens prosthetic rehabilitation, leading to compromised treatment planning.
Temporary Splinting in secondary trauma from occlusion followed by vestibular...dbpublications
Background: A 27 year old female patient presented with the chief complaint of pain and mobility in mandibular anterior teeth. An extremely shallow vestibule with less width of attached gingiva was observed with marginal gingival recession in 31, 32 and 41. Secondary trauma from occlusion was observed clinically with respect to 31. Methods: After adequate oral prophylaxis, the trauma from occlusion on 31 was relieved by selective grinding. The mobile mandibular anterior teeth were splinted with a temporary splint material (26 gauge stainless steel wire). The mandibular labial vestibule was extended using the lip switch procedure or the Edlan-Mejchar technique. Results: The procedure yielded a considerable gain in the width of the attached gingiva, which maintained itself even 9 months after the surgical procedure. Mobility was reduced with complete resolution of injury to the supporting tissues leading to improved function of the mandibular anterior teeth. Conclusion: Patients presenting with secondary trauma from occlusion and a shallow vestibule, treatment options such as oral prophylaxis, selective grinding, splinting combined with Edlan-Mejchar technique leads to complete resolution of mobility along with maintenance of the width of the attached gingival for a considerable period of time.
Simultaneous vertical guided bone regeneration and guided tissue regeneration...threea3a
This clinical case report describes using recombinant human platelet-derived growth factor (rhPDGF-BB) along with autogenous bone and barrier membranes to reconstruct severe alveolar bone defects in the posterior maxilla through simultaneous vertical ridge augmentation and sinus floor elevation. Over 9 months of healing, complete vertical bone regeneration and new attachment to a previously denuded root surface were observed. Three implants were successfully placed and a fixed restoration was provided, demonstrating the potential for rhPDGF-BB to enhance regeneration when combined with standard bone grafting techniques and membranes. However, further controlled studies are needed to fully evaluate the benefits of using rhPDGF-BB for complex reconstruction procedures.

This case report describes the full mouth rehabilitation of a patient with short clinical crowns in the mandibular anterior teeth and edentulous maxilla. A thorough examination including diagnostic wax-up determined 2mm of additional crown length was needed via crown lengthening surgery. Single crowns were placed on the anterior teeth along with a maxillary complete denture and mandibular removable partial denture with a lingual plate. The treatment aimed to prevent extrusion of the anterior teeth and reduce forces on the maxilla to avoid combination syndrome. A 4 month recall found healthy gingiva and the patient was satisfied with function and esthetics.
SOCKET PRESERVATION TECHNIQUE- A Case Presentation.pptxAshokKp4
This case report describes the use of a combined epithelialized-subepithelial connective tissue graft for socket preservation and ridge preservation after tooth extraction. The socket was grafted with a bone graft material. A connective tissue graft from the palate with an epithelialized layer was adapted to the socket dimensions and sutured into place. This provided primary closure of the socket to prevent bone and soft tissue loss. At follow-up after 6 months, the width and height of the ridge were maintained, demonstrating the effectiveness of this socket preservation technique using a combined soft tissue graft.

Rapid canine retraction and orthodontic treatment with dentoalveolar distract...Dr Mujtaba Ashraf
This document presents a study on a new technique called dentoalveolar distraction (DAD) to rapidly retract canines during orthodontic treatment. The study involved 10 patients where the maxillary first premolars were extracted and a distractor device was used to move the canines into the extraction sites at a rate of 0.8 mm per day. Full canine retraction was achieved in an average of 10 days with minimal anchorage loss. The canines tipped and translated distally on average 13 degrees. No complications were observed. The DAD technique reduces orthodontic treatment time by nearly 50% with no adverse effects on surrounding structures.
This case report describes a ridge splitting procedure combined with platelet rich fibrin (PRF) grafting and immediate implant placement in the maxillary anterior region. A 25-year old male patient presented with missing teeth in the area of teeth #11 and #12. Clinical examination and radiographs revealed 4-5mm of residual ridge width. Under local anesthesia, the ridge was split using chisels and osteotomes to expand the facial plate. A dental implant was placed and PRF prepared from the patient's blood was used to fill the gap between the cortical plates. Post-operative healing was uneventful and the implant osseointegrated successfully.

cameo surface recording in complete denture fabrication using TENS.pptxDhananjayVasuDeva2
- This clinical report describes a technique for improving the stability and outcome of a maxillary complete denture for a patient with severe resorption of the maxilla. The technique uses transcutaneous electrical nerve stimulation (TENS) to record the cameo surface of the denture bases while the muscles are stimulated.
- TENS was applied to stimulate the muscles of the perioral and buccal regions. A layer of adhesive and impression material was then applied to the trial denture base to capture the physiologically determined muscle position.
- The patient reported improved denture stability, retention and satisfaction over 2 years compared to previous dentures. Recording the cameo surface using TENS provides a reproducible alternative to manual mold
This study analyzed the position and angulation of 300 maxillary central incisors using cone beam imaging to provide data to help clinicians achieve good esthetic results for immediate dental implants. The thickness of buccal and palatal bone and apical bone height were measured. Incisors were classified according to their position (buccal, midline, palatal) and angulation (toward buccal, anterior to A point, parallel to alveolus). Most incisors were positioned buccally. Recommendations for implant placement based on tooth classification aim to maintain adequate buccal bone thickness and prevent complications.

hollow obturator in case of total maxillectomyDHANANJAYSHETH1
With the incorporation of neodymium magnets, the patient was able to insert and remove the 2-piece maxillary obturator prosthesis, engaging both the anterior and posterior undercuts without difficulty. This resulted in increased retention, stability, and improved speech and deglutition. At follow-up appointments, the patient expressed satisfaction with the prosthesis and gratitude that his chief complaints had been addressed.
This case series examines a new surgical technique for regenerating interimplant papillae using subepithelial connective tissue grafts. 10 patients with missing papillae between implant restorations received the new procedure involving buccal and palatal incisions made away from the papilla to preserve blood supply, and tunneling performed with a specialized instrument. The papillae scores improved on average from 0.8 to 2.4 after 16 months, demonstrating regeneration of the papillae over 11-30 months. However, long-term studies are still needed to validate the technique and outcomes.

It describes the twin table technique and twin stage procedure for fabricating restorations to achieve the proper cusp angles and anterior guidance. It provides standard values for effective cusp angles and discusses how to address deep overbites, anterior overjets, and open bites using principles of equilibration, splinting, and restoration.
This document discusses Hobo's philosophy on posterior disclusion and the twin-table technique for occlusal rehabilitation. Some key points:
- Hobo believed in posterior disclusion during eccentric movements, which is dependent on the angle of hinge rotation and inclination/shape of posterior cusps.
- The twin-table technique involves restoring posterior teeth with two sets of incisal tables - one without and one with disclusion.
- The twin-stage procedure is an advanced version that incorporates a kinematic formula to calculate anterior guidance from the condylar path. It allows reproduction of the standard amount of disclusion.
- Factors like cusp angle, anterior guidance inclination, and condylar path
Full mouth rehabilitation (FMR) involves extensive restorative procedures to modify the occlusal plane and accomplish equilibration. The goals of FMR are to establish a static centric occlusion in harmony with centric relation, evenly distribute stresses during function, and restore normal masticatory function. FMR is indicated for impaired occlusion, preserving remaining teeth, maintaining periodontal health, improving esthetics, and resolving pain. Diagnostic tools include study models, radiographs, photographs, and diagnostic wax-ups to develop the treatment plan.

This document summarizes a study that used intraoral sensors to objectively monitor patient compliance with stabilization splint therapy for myofascial pain. Some key findings:
- 32 patients were randomly assigned maxillary or mandibular splints equipped with sensors recording wear time.
- Overall compliance was 44.4% for maxillary and 44.2% for mandibular splints, with no significant difference between the groups.
- Patients with greater pain wore their splints significantly more. Wear time decreased over the 3 observation periods as pain reduced with treatment success.
- The study demonstrated intraoral sensors are an effective way to objectively monitor splint wear compared to subjective reports.
Journal club presentaion on zirconia fixed partial dentured on endodonticaloy...NAMITHA ANAND
The study investigated the effects of different post and core material combinations on surface strain of zirconia fixed partial denture (FPD) margins. Artificial abutment teeth were restored with either resin composite cores with glass fiber posts or cast metal alloy posts and cores. Strain gauges measured surface strain on the zirconia frameworks and abutment roots under static loading. The results showed that restoring the premolar with a cast post and core and the molar with a resin composite core reduced stress concentration in both the frameworks and abutment teeth compared to the other combination. The study suggests considering post and core material properties and differences in abutment tooth morphology when selecting materials for zirconia FPD
Sinus lift procedures. final copy of presentation pptxNAMITHA ANAND
This document discusses maxillary sinus lift procedures. It begins with the anatomy of the maxillary sinus, including its bony walls, blood supply, and Schneiderian membrane. It then covers clinical assessment of the sinus and various factors that can affect sinus health. The document discusses contraindications for sinus lift procedures and techniques for reducing complications. It also covers classifications of sinus lifts, different surgical techniques, potential intraoperative and postoperative complications, and instrumentation used. In summary, the document provides an overview of maxillary sinus anatomy and considerations, techniques, and risks associated with sinus lift procedures.
The document discusses various aspects of maxillary sinus lift procedures:
- The maxillary sinus presents challenges for implant placement due to poor bone density and height. Sinus lift procedures aim to increase bone height for implants.
- Factors like residual bone height/width, sinus pathology, anatomical variations, and buccal wall thickness influence sinus lift technique selection.
- A thorough preoperative exam is needed to assess sinus health and rule out infections or cysts, which may require treatment prior to sinus lift. Radiographs and CT scans help evaluate sinus anatomy and pathology.
JOURNAL CLUB PRESENTATION on lingualised occlusionNAMITHA ANAND
The document describes a case report of achieving a lingualized balanced occlusion in a fixed-removable rehabilitation for a patient with a maxillary complete denture and mandibular Kennedy Class II dentition. Key details include:
- The 64-year-old female patient presented with ill-fitting dentures and wanted improved esthetics and function. Examination revealed extensive tooth loss and wear.
- Treatment involved extracting remaining teeth, providing interim dentures, and eventually a maxillary complete denture opposed by a lingualized occlusion with mandibular fixed partial denture and removable partial denture.
- Using a semiadjustable articulator and compensating curve template ensured the desired occlusal plane and
Journal club presentation on lingualised occlusionNAMITHA ANAND
This case report describes the rehabilitation of a patient with a maxillary complete denture and mandibular removable partial denture opposing fixed restorations. A lingualized balanced occlusion scheme was used to harmonize occlusion between the fixed and removable elements. An articulator and 2.5D template were used to set up the occlusion and establish centric and eccentric contacts. Porcelain fused to metal crowns were fabricated for abutment teeth along with a metal framework removable partial denture for the mandibular arch. The treatment resulted in a lingualized balanced occlusion with minimal adjustments needed at delivery.

- The Andrews Bridge System is a fixed-removable partial denture that combines fixed retainers connected by a bar with removable pontics for esthetic rehabilitation of edentulous ridges.
- Advantages include improved esthetics, hygiene, phonetics and stress distribution compared to removable partial dentures.
- A clinical case report describes using the system to restore a patient missing maxillary and mandibular anterior teeth following trauma. Post-treatment, the patient had pleasing esthetics and function.
prosthodontic management of maxillectomy/obturators part 2 final copyNAMITHA ANAND
This document discusses implant placement and rehabilitation of maxillectomy defects. Some key points include:
- Implants can be placed in residual bone of the anterior maxilla, tuberosity, pterygoid plates, or zygomatic arches to aid in retention of obturator prostheses.
- Survival rates are lower in irradiated patients and anterior maxilla. Posterior implants have higher survival.
- Bone loss can occur if implants receive excessive occlusal forces.
- Tissue bar attachments are commonly used to connect implants and aid in prosthesis support and stability.
- Zygomatic implants can be used in large defects but oral hygiene is difficult.
PROSTHODONTIC MANAGEMENT OF MAXILLECTOMY/ OBTURATORS PART 2NAMITHA ANAND
This document discusses the rehabilitation of maxillectomy defects through implant-retained prostheses. It describes how implants can be placed in residual bone such as the anterior maxilla, tuberosity, zygomatic arches and pterygoid plates to aid in retaining prostheses. Placement in the anterior maxilla often leads to bone loss due to excessive forces while placement in the tuberosity has higher failure rates. Tissue bar attachments are recommended to distribute forces along the implant axes. The document outlines the surgical and prosthodontic procedures for fabricating implant-retained obturator prostheses.

Prosthetic options in implant dentistryNAMITHA ANAND
This document discusses various prosthetic options in implant dentistry. It begins by introducing different treatment options for completely and partially edentulous patients, noting that implant dentistry provides more options compared to traditional dentistry. It then covers Misch's classification system for prosthetic options (FP1-FP3, RP4-RP5), which are determined by the amount of hard and soft tissue replacement needed. The document discusses different prosthesis types for complete and partial edentulism in detail. It also covers considerations for prosthesis design such as crown height space, bone width, implant positioning and restorative materials. In conclusion, the optimal prosthetic option depends on the patient's existing oral condition and treatment goals.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Zhao et al. studied the effect of using PRF as a sole grafting material, and they
found it to preserve the alveolar ridge.
PRF was used as a sole graft material for both socket packing and to increase
the alveolar ridge height; hence, the first benefit is given by improving the
esthetic appearance instead of waiting the gingiva to fill the gap, and this
provides greater comfort to the patient in the postoperative period as well as

36. Patients were assessed both clinically and radio logically pre
operatively and 3 months post operatively. Computed tomograms
were used for radiographic assessment by comparing the area
measurements obtained using the VOLUME TOOL , SYNGO
SOLARIS 7 software, from pre-operative and three months post-
operative scans
41. Results
Clinically pain, swelling, wound dehiscence, and implant exposure was
assessed. Pain and swelling was present in some cases on third post-
operative day. Loss of graft in one patient was observed which was
removed completely maintaining the primary stability of the implant.
Results suggested substantial increase in the volume wise measurements
when pre-operative and three-month postoperative results were
compared
42. Conclusion
PRF is efficacious clinically and radiographically in the treatment of a peri-
implant defect. PRF is an autologous preparation and found to be clinically
effective and economical than any other available regenerative materials
and is more fruitful when used along with PCL. However, long term,
multicenter randomized, controlled clinical trial will be required to know its

58. Conclusions
After 6 months, all 31 implants were osteointegrated.
Soft tissue augmentation with PRF led to a significant tissue loss.
crestal mucosa in the control group showed higher stability
For ethical reasons, the test group was terminated after 10 cases, and
the remaining cases were finished within the control group.
Within the limits of this study and the early determination of the test
group, this study concludes that soft tissue augmentation with PRF
performed with a split-flap technique cannot be recommended for
thickening thin mucosa. Further studies focusing on different
techniques and longer follow-ups are needed to evaluate whether PRF
is suitable for soft tissue thickening.

60. This study wants to
demonstrate how PRF in
association with a new split
crest augmentation
technique can be a great
aid in implant rehabilitation,
especially in the elderly
patients, when bone
regeneration is required
AIM
61. Ten patients were treated in this study, five following the flapless split crest new procedure and other
five patients following traditional procedure without split crest as control.
Five patients with an average age between 50 and 60 years were selected to be operated with a split
crest flapless modified technique in order to optimize the regenerative conditions with a bone
augmentation and implant insertion in one single stage procedure. For all the patients autologous
PRF has been used to fill the split crest gap or simply as regenerative material
64. RESULTS
All cases were successful, there were no problems at surgery time, at post-
operative and at osteointegration periods. All implants achieved
osteointegration. These results were obtained by accu-rately managing
immediate and late post operative period in all of the operated cases.
Mean difference for height bone loss between the two groups of patients
was 2.4 mm at T1 and 2.2 mm at T3.
65. DISCUSSION
The rationale of this split crest flapless modified technique is to obtain a
proper buccal cortex expansion preserving its vascular supply avoiding
periosteal elevation for better cortical bone nourishing. Moreover,
advantages are reported related to the use of PRF. The effectiveness of PRF
is shown in promoting the healing of surgical wounds, it has, in fact,
platelet growth factors that can improve the vascularisation of the surgical
site, promoting neoangiogenesis. Furthermore, by simply changing the
settings of the centrifuge, it is possible to obtain a normal gelling if it has
to be used as regenerative and stimulating material, or more consistent
substance to be used as a filler in the split crest gap.
66. CONCLUSION
The main advantages in using the platelet-rich fibrin are healing and bone
regenerativeproperties in combination with its complete resorption after
surgery, thus avoiding a second surgerytime, important factor in the
elderly patients. Currently, it is a minimally invasive technique with lowrisks
and satisfactory clinical results such preventing complications or implant
failure particularly inelderly patients for age related conditions

Editor's Notes
It is exceptionally challenging for any clinician in the esthetic zone as the expectations are significantly increased.

To overcome such a problem and to restore the ridge contour to more favorable situation, some authors proposed the

These alveolar ridge augmenting and regenerative procedures could enhance the esthetic result of fixed partial denture (FPDs) by avoiding the need to include a long, anesthetic pontic in the prosthesis design.

After ensuring the stabilization of the membrane, the final wash of the surgical site using povidone-iodine solution was done. Postoperative intraoral periapical radiograph was taken, confirming the accuracy of the placement of implants. Abutments were attached to the implant body and prepared for parallelism and adequate space. At the same day, Postoperative care included soft diet and 0.12% chlorhexidine gluconate mouthwash twice daily starting from the next day. Systemic antibiotic and analgesic regimen including Augmentin (625 mg) TID for 5 days and the tablet Enzoflam D TID for 3 days were prescribed.
A postoperative OPG was taken, and the patient was recalled after 1 week for follow-up
Radiographic evaluation revealed good osseointegration.
