This document discusses computer guided treatment planning and implant placement. It describes how computer guided planning allows visualization of potential implant sites in 3D and more precise placement compared to free-hand drilling. Fully guided surgery uses surgical templates to control position, angle, depth and diameter of osteotomies, while semi-guided surgery controls initial position and angle only, allowing more flexibility. Fully guided is used for edentulous patients, while semi-guided is preferred for partially edentulous patients where soft tissue manipulation or bone grafting may be needed.
This document discusses factors that affect dental implant design, including the magnitude, duration, and type of forces applied to implants. It describes design elements like thread geometry, pitch, depth, and taper that influence stability, load distribution, and surgical placement. Overall, the optimal implant design considers surgical technique, limiting bacterial plaque, preserving bone levels, and withstanding functional forces through features like screw threads that engage bone under compression rather than shear.

Dental Implants
Dental illustration by Dear Doctor
Let’s start from the beginning: A dental implant is actually a replacement for the root or roots of a tooth. Like tooth roots, dental implants are secured in the jawbone and are not visible once surgically placed. They are used to secure crowns (the parts of teeth seen in the mouth), bridgework or dentures by a variety of means. They are made of titanium, which is lightweight, strong and biocompatible, which means that it is not rejected by the body. Titanium and titanium alloys are the most widely used metals in both dental and other bone implants, such as orthopedic joint replacements. Dental implants have the highest success rate of any implanted surgical device.
Titanium’s special property of fusing to bone, called osseointegration (“osseo” – bone; “integration” – fusion or joining with), is the biological basis of dental implant success. That’s because when teeth are lost, the bone that supported those teeth is lost too. Placing dental implants stabilizes bone, preventing its loss. Along with replacing lost teeth, implants help maintain the jawbone’s shape and density. This means they also support the facial skeleton and, indirectly, the soft tissue structures — gum tissues, cheeks and lips. Dental implants help you eat, chew, smile, talk and look completely natural. This functionality imparts social, psychological and physical well-being.
This document discusses maxillofacial prosthetics, which are artificial devices used to replace missing facial or oral structures. It describes various types of maxillofacial defects including cleft lip and palate, acquired defects from surgery or trauma, and extraoral defects. The goals of maxillofacial prosthetics are to preserve remaining structures, reconstruct function, and improve aesthetics. Common materials used include silicone, acrylic, and metals.

Journal club presentation on tooth supported overdentures NAMITHA ANAND
This document presents a case report of a full mouth rehabilitation with an immediate maxillary denture and a mandibular tooth-supported magnet-retained overdenture. Specifically:
- A 43-year old female patient presented with missing teeth in the upper back region and multiple missing teeth in the lower arch.
- For rehabilitation, the maxillary teeth were extracted and an immediate denture placed. In the mandible, several teeth were prepared to receive magnetic attachments or copings.
- At the insertion appointment, the remaining maxillary teeth were extracted and the denture was relined. In the mandible, magnets were incorporated into the overdenture to attach it to the prepared teeth.
Implant abutment and implant abutment connectionsDR.BHAVESH JHA
this ppt enlightened with different types of implant abutment connection. Detailed classification of abutments. Different types of abutments. Latest trends of abutments. Smart abutments. Platform switching, rationale of platform switching and related articles.
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.
horizontal jaw relation in complete denturedipalmawani91
This document provides an overview of centric relation and how its definition has changed over time. It discusses the significance of centric relation as a reference position and reviews various theories about how it is achieved musculoskeletally. The document also examines the relationship between centric relation and centric occlusion, and describes different methods for recording centric relation, including static, functional, graphic, and physiological techniques. Factors that can influence the accuracy of centric relation records are also reviewed.
The document discusses bone density and its importance in implant dentistry. It describes four classifications of bone density (D1-D4) based on macroscopic characteristics, with D1 being the densest. The anterior mandible typically has the densest D1/D2 bone, while the posterior maxilla has the least dense D4 bone. Determining bone density accurately using CT scans is important for developing an appropriate treatment plan and ensuring implant success long-term by avoiding pathological overload conditions.
An impression is required to fabricate a fixed dental prosthesis. It must include the prepared teeth as well as surrounding structures. Various impression materials and techniques have been developed over time. Today, alginate, polyether, addition silicone and polyvinyl siloxane are commonly used. Proper tray selection and customization is important to obtain an accurate impression. Impression making requires isolation, tissue retraction and meticulous technique to ensure detail and avoid imperfections.
This document discusses the prosthodontic rehabilitation of patients who have undergone mandibulectomy. It describes different classifications of mandibular defects and the goals of mandibular reconstruction. Key diagnostic considerations for prosthodontic treatment are discussed such as the location and extent of the defect, remaining teeth, jaw rotation, and mouth opening. Surgical reconstruction techniques and approaches to rehabilitation for partially or fully edentulous patients are presented, including the use of implants, guidance prostheses, and overlay dentures. Close follow-up is important when rehabilitating mandibulectomy patients prosthodontically.

This document discusses the All on Four and All on Six dental implant concepts. It provides background on conventional rehabilitation approaches and challenges with atrophic jaws. Tilted implants are introduced as an alternative that places implants at an angle to bypass anatomical structures and increase prosthetic support. The All on Four concept involves placing four implants total, two in the front and two in the back at an angle, to support a fixed full-arch dental prosthesis. Advantages include avoiding complex surgery, providing immediate function, and reducing costs compared to other approaches. Treatment planning considerations and protocols for the surgical and prosthetic phases are outlined.
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).
This is a power point presentation on sinus floor elevation, describing the various techniques, biological aspects and clinical outcomes from a periodontist point of view. It also includes a brief review on the anatomy of maxillary sinus and management of complications.
The document discusses pontic design for fixed dental prostheses. It covers pretreatment assessment of residual ridge contours, classifications of ridge deformities, surgical modification techniques, and ideal requirements for pontics. Pontic designs are classified based on their shape and materials. Factors in pontic selection include esthetics and oral hygiene. Common designs for anterior and posterior regions are described, including sanitary, ovate, and saddle pontics. Biological considerations for pontic design involve maintaining the residual ridge, abutment teeth, and supporting tissues.
Dento-alveolar fractures involve avulsion, subluxation or fracture of the teeth associated with a fracture of the alveolus. They are commonly caused by road traffic accidents or falls and more frequently affect the maxillary central incisors in children. Treatment depends on the complexity and location of the injury, with goals of preserving damaged teeth when possible through splinting or endodontic treatment. Management may include extraction, repositioning displaced teeth, and repair of soft tissue or alveolar bone injuries.
This document discusses dentoalveolar injuries, which are injuries limited to the teeth and supporting structures of the alveolus. It defines various types of dentoalveolar injuries including concussions, subluxations, luxations, and avulsions. For each type of injury, it describes the diagnosis, classification, and treatment recommendations. Treatment depends on factors like the stage of root development, presence of fractures, and degree of tooth displacement. In general, immediate repositioning and splinting is recommended for displaced teeth, while avulsed teeth should be cleaned and stored in milk before replantation with splinting and antibiotics.

Maxillofacial prosthetics aims to restore function and aesthetics after defects caused by trauma, surgery, or congenital conditions. It involves both intraoral and extraoral prostheses made of materials like acrylics and silicone. Immediate prostheses are placed during or right after surgery to aid healing, while definitive prostheses are placed months later once healing is complete. Preprosthetic measures like vestibuloplasty and implants can improve prosthetic outcomes. The goal of extraoral prostheses for areas like the ear, orbit, and nose is cosmetic restoration through careful design and skin grafting or implant support if needed.
This document describes various extraoral approaches to the mandible, including the submandibular approach. The submandibular approach involves making an incision 1-2 cm below the mandible. Key anatomical structures like the facial artery and vein and marginal mandibular nerve are discussed. The technique involves incising skin and platysma muscle before dissecting through layers to expose the mandible. Care must be taken to protect important nerves and vessels during the dissection.
Mandibular fractures have been documented since ancient Greece. Hippocrates described reducing displaced but incomplete mandibular fractures by pressing on the lingual surface with fingers while applying counterpressure externally. The Edwin Smith Treatise also described examining for mandibular fractures by feeling for crepitus under the fingers. Mandibular fractures typically involve the body, angle, condyle, symphysis, or ramus. Physical exam may reveal changes in occlusion, inability to open or close the mouth, anesthesia of the lower lip, or trismus. Diagnosis is made by identifying these physical exam findings along with the patient's mechanism of injury.
This document provides an overview of orthopedic appliances used to modify maxillary and mandibular growth. It discusses the principles, types (e.g. headgear, facemask), biomechanics, and clinical applications of these extraoral appliances. Key points covered include the magnitudes, durations, and directions of optimal orthopedic forces; the use of headgears like cervical pull, high pull, and combinations; and the goals of growth modification to alter skeletal relationships and avoid surgery.

How to Fix the Import Error in the Odoo 17Celine George
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.
Strategies for Effective Upskilling is a presentation by Chinwendu Peace in a Your Skill Boost Masterclass organisation by the Excellence Foundation for South Sudan on 08th and 09th June 2024 from 1 PM to 3 PM on each day.
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
it describes the bony anatomy including the femoral head , acetabulum, labrum . also discusses the capsule , ligaments . muscle that act on the hip joint and the range of motion are outlined. factors affecting hip joint stability and weight transmission through the joint are summarized.
2. Introduction.
• What is Maxillofacial prosthetics ?
It is the art and science of anatomic,
functional, or cosmetic reconstruction by
means of non living substitutes of those
regions in the maxilla,mandible, and face
that are missing or defective because of
surgical intervention, trauma, pathology, or
developmental or congenital malformation.
www.indiandentalacademy.com
3. Objectives of maxillofacial
prosthetics.
1) Restoration of Esthetics or Cosmetic
appearance of the patient.
2) Restoration of function.
3) Protection of tissues.
4) Therapeutic or healing effect.
5) Psychologic therapy.
www.indiandentalacademy.com
4. Prosthetics Vs Plastic surgery.
• Maxillofacial prosthetist normally provides
appliances and devices to restore esthetics and
function to the patient who cannot be restored to
normal appearance or function by means of
plastic reconstruction
• Limitations for plastic surgery:
1. Advanced age of patient.
2. Poor health
3. Very large deformity
4. Poor blood supply on post-radiated tissue.
5. Systemic diseases.
6. Economic conditions.
www.indiandentalacademy.com
5. Team approach.
1. Maxillofacial prosthodontist.
2. The surgeon.
3. The radiotherapist.
4. The speech therapist.
5. The psychiatrist.
6. The social worker.
7. Other dental specialists.
www.indiandentalacademy.com
8. Materials used in maxillofacial
prosthetics.
www.indiandentalacademy.com
9. Retention of prosthesis.
• Close evaluation of a case with the surgeon
before and during surgery helps in finding
means to create irregular defects for
enhancing anatomic retention
www.indiandentalacademy.com
10. Retention in Intraoral prosthesis.
• Anatomic retention- By Teeth, Mucosal and
bony tissues.
Factors aiding in anatomic retention
– Anatomic undercuts –
– Large alveolar ridges
– High palatal vaults.
– Proper occlusion.
– Proper post dam
– Surface adhesion
www.indiandentalacademy.com
11. Mechanical retention
• Temporary
– different clasps made of wrought wire.
– Preformed stainless steel bands or crowns
• Permanent mechanical retention
– Cast clasps.
– Precision attachments:Prefabricated and custom made.
– Snap on attachment
– Telescopic crowns and thimble crown.
– Gate type or swing lock devices
– Intermaxillary “george washington” springs
– Screws,Implants,Suction cups,Adhesives, Magnets and
occlusion.
www.indiandentalacademy.com
12. Extraoral retention.
• Anatomic retention.
– Hard tissues act as a base against which to seat the
prosthesis.
– Soft tissues
• Mechanical retention.
– Magents
– Eyeglasses
– Snap buttons and straps
– adhesives
www.indiandentalacademy.com
13. Intraoral prosthesis
• Obturators
– a prosthesis used to close a congenital or
acquired tissue opening ,primarily of the
hard palate and /or contiguous alveolar
structures.
– Prosthetic restorations of the defect often
includes use of a surgical obturator,
interim obturator, and definitive
obturator.
www.indiandentalacademy.com
14. Functions of obturator
1) keeps the wound area clean and to enhance healing
2) To reshape or reconstruct the palatal contour/or soft
palate
3) Improves speech
4) Can be used to correct lip and cheek position
5) Improves mastication.
6) Reduces the flow of exudates in the mouth
www.indiandentalacademy.com
15. Classification :-
Congenital Defects Acquired Defects
•Simple obturator
•Simple with Velopharyngeal extn..
•Overlay or a super imposed denture.
•Surgical obturator.
•Interim obturator
•Definitive obturator
www.indiandentalacademy.com
17. Surgical obturator
• Facilitates oral function
immediately after surgery,
• Patient may regain speech
within a normal range .
• Wrought wire clasps are used .
• Constructed from preoperative
impression cast.
• It eliminates the need for the
nasogastric tube.
• It can serve as matrix for
surgical dressing.
www.indiandentalacademy.com
18. Temporary obturator
• After 7-10 days ,the prosthesis is removed and
reprocessed with new acrylic resin.this becomes a
temporary obturator and serves for 4-6 months of
healing period.
• Periodic modifications with tissue conditioners
• Multiple wrought wire clasps are used
• Mastication on the surgical side are avoided
• Prosthetic teeth may be added to enhance
esthetics.
www.indiandentalacademy.com
19. Definitive obturator.
• Constructed from the post surgical
maxillary cast.
• Has a false palate ,false ridge ,teeth ,and a
closed bulb which is hollow.
www.indiandentalacademy.com
26. Quality of retention depends on
• Muscular control.
• Size of surgical cavity
• availability of tissue undercut around the
cavity
• Direct and indirect retention provided by
any remaining teeth.
www.indiandentalacademy.com
27. Retentive regions are
• Fibrous tissue scar bands in the buccal
sulcus.
• Rolled edge of the palatal remnants
• Base of the nasal mucosa of the nasal
septum.
www.indiandentalacademy.com
28. Forces on Obturators
These forces can be
• Vertical dislodging force
• Occlusal vertical force
• Torque or rotational force
• Lateral force
• Anterior posterior force.
www.indiandentalacademy.com
29. dislodging and rotational forces
The weight of the nasal extension of the
obturator exerts dislodging and rotational
forces on abutment teeth.
To resist these forces
-weight of the obturator be minimal
-direct retention
-extending the buccal wall of the
nasal extension superiorly.
www.indiandentalacademy.com
30. Relation of the scar band to the
lateral portion of the obturator.
• Buccal scar band will
develop at height of
previous vestibule
where buccal mucosa
and skin graft in
surgical defect join.
www.indiandentalacademy.com
31. Surgical considerations
• Efforts should be directed towards
conversion a potential class I maxillary
defect into a class II defect to provide a
superior prosthesis both functionally and
esthetically.
www.indiandentalacademy.com
32. Recommendations to surgeon.
1. Preservation of the contra lateral anterior
teeth,if it does not compromise tumor
eradication.
2. If the palatal mucosa is not invaded by the
tumor,it is preserved and reflected to
cover the medial wall. this procedure
provides superior tissue quality coverage
for the nasal septum.
www.indiandentalacademy.com
33. 3. Preservation of the posterior hard plate on
the defect side if the tumor is situated
anteriorly or laterally.
4. Resection through the socket of the tooth
closest to the specimen allows for
maintenance of the proximal alveolar
bone adjacent to the abutment tooth.
www.indiandentalacademy.com
34. Classification of Obturators
According to Origin of discrepancy :
- congenital
– acquired
According to Location of defect
According to physiological movement of the
surrounding tissue.
a. Static obturator
b. Functional obturator.
www.indiandentalacademy.com
35. Factors to consider for superior
height of bulb.
1. If patients speech cannot be understood the bulb
should be extended upward.
2. With maxillary resection much of the bone
support for the cheek is removed.the obturator
bulb height will reestablish this contour.
3. According to brown (1968) height of the bulb
relates to the retention of the completed
obturator.
4. Amount of Mouth opening of the patient
www.indiandentalacademy.com
37. Speech aids
• These are prosthesis that are functionally
shaped to the velopharyngeal musculature
to restore or compensate for areas of the
soft palate that are deficient because of
surgery or congenital anomaly.
www.indiandentalacademy.com
38. Palatal augmentation
• If a part of tongue is lost ,the ability of the
tongue to reach the palate for appropriate
speech and swallowing is compromised.
• The contour of palate can be augmented by
a prosthesis to fill the space of donder so
that a food bolus can be more easily moved
posteriorly into the oropharynx.
www.indiandentalacademy.com
39. Reasons of eye loss.
• Cancer , e.g. Retinoblastoma.
• Trauma
• Congenital birth deficiency
• Blind painful eye
www.indiandentalacademy.com
40. Evisceration
• The muscles that
control eye movement
remain attached to the
sclera.
• Evisceration generally
gives better movement
to the ocular prosthesis
(artificial eye).
www.indiandentalacademy.com
41. This is a 7 year old child who
came to dept of prosthodontics

Types of eye surgery and their
corresponding prosthesis
www.indiandentalacademy.com
43. • Ocular prosthesis
– An ocular prosthesis is an
artificial replacement for
the Bulb of the eye.
• Orbital prosthesis
– When the entire contents
of the orbitare removed-
the artificial replacement
is referred to as an orbital
prosthesis.
www.indiandentalacademy.com
44. Eye as focus of attention

45. Aims/Advantages of eye
prosthesis
1. Comfort
2. Cosmetics- Restore facial contour.
3. Bony Orbital Wall, and Eyelid development.
4. To maintain the volume of the eye socket
5. Protects delicate tissues and maintains proper
humidity for Mucosa or orbital structures.
6. Provides a great psychological benefit in the
rehabilitation of the patient.
7. Quick and early adjustment to monocular vision.

47. Impression
• Areas for impression defined and boxed.
Length –from forehead down to
the top lip.
Breadth - from tragus to tragus.
• Impression procedure.
• Pouring the impression.
www.indiandentalacademy.com
49. Eyeball component
• The eyeball component
is custom designed and
fabricated in acrylic, with
regard to size and
colour, to match the
contra lateral eye, as
closely as possible.
www.indiandentalacademy.com
50. Eye alignment
• Eye must be in exactly the right position or the
prosthesis will look strange and unreal.
• Determining factors
-Inter-pupillary distance
-Back vertex alignment
-Horizontal alignment
www.indiandentalacademy.com
51. • Sculpting
– Great care is taken during
carving of the prosthesis
so as to 'capture' the most
constant appearance.
– It is done with the patient
present .
• Color matching
• Finishing
• Eyelashes and eyebrows
are added
www.indiandentalacademy.com
52. Spectacle considerations
• The frame should mask as
much of the margins as
possible .
• Patients with orbital defects
are advised to wear lightly
tinted glasses to help hide the
prosthetic margins and
disguise that there is no
movement in the prosthetic
eye.
• Hinge of the spectacle arm is
locked to prevent any
accidental opening .
www.indiandentalacademy.com
54. Limitations
•It will take some time to adjust to using one
eye, but almost all patients learn to
compensate during the first year after surgery.
•The socket will grow with age and hence the
need for new prosthesis frequently.
•Since the extraocular muscles are not
attached to the prosthesis, it does not move as
a natural eye.
•Almost all patients learn to compensate during the
first year after surgery.

Determine the best close for your audience and your presentation. Close with a summary; offer options; recommend a strategy; suggest a plan; set a goal. Keep your focus throughout your presentation, and you will more likely achieve your purpose.
The most common causes of one or both eye loss are cancers such as retinoblastoma,trauma,congenital birth deficiency,blind painful eye.
In evisceration the contents of the eye (iris, lens, vitreous, retina, and choroid) are removed leaving behind a pocket of sclera. The muscles that control eye movement remain attached to the sclera and as a result evisceration generally gives better movement to the ocular prosthesis. The child is fit for a ocular prosthesis 4-6 weeks after the operation.
so enucleation and evisceration warrent ocular prosthesis and exentration needs an orbital prosthesis .
An ocular prosthesis is an artificial replacement for the Bulb of the eye.it is indicated in enucleation and evisceration.
This diagram is created from a photograph of a face . superimposed on the second picture are the recorded eye movements of a person observing this face. The movements show how much time an observer’s eyes search the eyes of the person observed. this highlights the importance of the eyes in social interactions.
An eye prosthesis provides Comfort, Cosmetics, Restore facial contour.
Helps in Continued Bony Orbital Wall, and Eyelid development and also
maintains the volume of the eye socket
Acrylic as a prosthetic material gives Artificial look,is lighter,and affordable and easily availble.silicone gives More natural look, is heavy and Expensive.
A partial impression of the face usually suffice instead of full impression.Patient is placed on the chair in supine position.Towels placed to protect clothes from spillage.Tissue undercuts are packed with Vaseline gauze.
A base plate is adapted to the model –it can be of acrylic or wax .Identifying the margin areas of the prosthesis and trimming the base accordingly.
The eyeball component is custom designed and fabricated in acrylic, with regard to size and colour, to match the contra lateral eye, as closely as possible.
Eye must be in exactly the right position or the prosthesis will look strange and unreal.Determining factors are -Inter-pupillary distance ,-Back vertex alignment and -Horizontal alignment .
Great care is taken during carving of the prosthesis so as to 'capture' the most constant appearance.
Prosthesis and spectacles are attached with self cure acrylic. Hinge of the spectacle arm is locked with self cure acrylic to prevent any accidental opening.
It will take some time to adjust to using one eye, but almost all patients learn to compensate during the first year after surgery.The socket will grow with age and hence the need for new prosthesis frequently. Since the extraocular muscles are not attached to the prosthesis, it does not move as a natural eye.
