The document discusses the development of a new implant called the Co-Axis implant, which is designed to be placed at an angle to avoid anatomical structures. The Co-Axis implant has built-in 12 and 24 degree angles and uses the existing surgical protocol and components. Tilted implants can eliminate grafting procedures and decrease treatment time and cost. Studies have shown tilted implants can work long term if primary stability is achieved.
Dental implants can be modified at the macro, micro, and nano levels to improve osseointegration and healing times. At the macro level, implant thread design is modified. Micro level modifications alter the surface topography through processes like sandblasting and acid etching. Nano level modifications increase the surface area through additions like titanium nanotubes. Coatings of hydroxyapatite and other calcium phosphates are also used at the micro and nano scales to promote bioactivity. Surface modifications generally increase roughness and research shows rougher surfaces correlate with higher success rates.
The document discusses various impression techniques used for dental implants. It describes the key components used, such as implant analogues and impression copings. The most common impression materials are vinyl polysiloxanes and polyether rubbers due to their dimensional stability and detail reproduction. Direct open tray techniques involve exposing the impression coping screws and incorporating the copings into the impression tray. Indirect closed tray techniques retain the copings in the mouth and reattach them to analogues in the lab. Factors like implant angulation, number of implants, and interarch space determine whether open or closed tray methods are preferred. Accurate transfer of the implant positions is crucial for passive fitting of the final prosthesis.
This document discusses guided bone regeneration (GBR), a surgical procedure that uses a membrane barrier to exclude soft tissues and promote bone growth in a defect site. It provides background on GBR and guided tissue regeneration, reviews pioneering animal and human studies demonstrating the efficacy of GBR using membranes like e-PTFE, and discusses principles, indications, clinical procedures, and membrane types used in GBR. Key GBR principles include cell exclusion, tenting, scaffolding, stabilization, and framework to support new bone formation.

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.
This document discusses osseointegration, which refers to the direct structural and functional connection between bone and the surface of a load-bearing dental implant without intervening soft tissue. It traces the history and development of osseointegration from early experiments in the 1950s to its current understanding. The key aspects covered include definitions of osseointegration, the biological process of bone formation around implants over time, factors that influence osseointegration success, and future directions for improving integration.

The biological fixation determines the longevity of dental implant treatment. It ensures the long term survival of dental implant. Better the osseointegration,higher will be the survival rate
This document discusses biomechanics as it relates to implantology. It defines key biomechanical concepts such as force, stress, strain and their relationships. Forces on dental implants can come from biting or parafunctional habits and are made up of compressive, tensile and shear components. The magnitude of stress on implants is determined by the applied force and the cross-sectional area over which it is distributed. Maintaining low stress levels is important for long-term implant success and minimizing risk of failure. Biting forces on natural teeth can range from 100-2400 Newtons and impact loads present additional risk. Biomechanical principles guide optimal implant design and placement to ensure forces are properly dissipated.

The document discusses various designs of dental implants. It describes the history of dental implants from ancient times to modern osseointegrated implants developed by Brånemark in the 1950s. It then classifies implant designs based on type of placement (e.g. endosteal, subperiosteal), macroscopic body design (e.g. cylindrical, threaded), and components (e.g. crest module, body, apex). Key design considerations discussed include thread pitch, shape and depth, implant diameter and length, and one-piece versus two-piece designs.
Dental implants can replace missing teeth by surgically placing artificial titanium fixtures into the jawbone. There are typically two surgical phases - the initial implant placement and a later surgery to uncover the implant after healing. The implant then receives an abutment and final prosthetic restoration. While dental implants can provide many benefits over other tooth replacement options, there are also potential complications at various stages that a dentist must take steps to prevent and manage. Proper patient evaluation, surgical planning and technique, as well as post-operative care are important to achieve successful long-term outcomes.
The document discusses various factors that can contribute to dental implant failures, including host factors like poor medical health, smoking, bruxism, and poor oral hygiene; surgical factors like trauma during surgery; and implant selection factors like bone quality. It provides definitions for different types of implant failures and lists criteria for determining implant success. The classifications, predictors, warning signs, and ways to enhance outcomes with implants are also examined.
This document discusses dental implants and the importance of soft tissue and bone health for implant success. It covers topics like osseointegration between implants and bone, gingival shrinkage during healing, the peri-implant soft tissue seal, the need for keratinized gingiva, and maintaining the biological width of peri-implant soft tissues. Patient factors like age, smoking, and diseases as well as local bone quality can influence implant success. Proper implant placement and surgical technique are important to support the overlying soft tissues long-term.
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.

This document discusses osseointegration, which is the direct structural and functional connection between living bone and the surface of a load-carrying dental implant without intervening connective tissue. It covers the history, definitions, theories, mechanisms, and factors affecting osseointegration. The key points are that osseointegration was discovered by Branemark in the 1950s and involves new bone formation directly on implant surfaces through osteoconduction and remodeling over time to achieve a stable implant-bone interface. Factors like implant design, surface, material biocompatibility, and surgical technique influence the degree of osseointegration.
Basic Surgical Techniques for Endosseous Implant Placement discusses the history and process of dental implants. It describes how Branemark discovered that titanium bonds directly to living bone, called osseointegration. The document outlines the 4 steps of a typical surgical procedure: 1) initial surgery, 2) osseointegration period, 3) abutment connection, and 4) final prosthetic restoration. It also discusses factors that influence osseointegration like biocompatible materials and atraumatic surgery.
Dental implants can replace missing teeth and preserve jawbone structure. Implants integrate securely with jawbone, providing stability, function, and aesthetics like natural teeth. Without tooth roots, jawbone deteriorates over time. Tooth loss impacts confidence and function by allowing other teeth to shift out of place. Dental implants are the best solution to replace missing teeth and prevent bone loss long term. The document outlines implant treatment procedures and shows examples of implant-supported restorations.
The document discusses implant dentistry and implant prosthetics. It covers topics such as reasons for dental implants, implant placement techniques, impressions, fixed and removable implant prostheses, and occlusion considerations. Implant placement can be done using two-stage or single-stage surgical protocols. Impressions can be taken at the fixture or abutment level using closed or open tray techniques. Restorations can be cement-retained or screw-retained. Proper occlusion is important to minimize risks and maximize function.
The document discusses immediate loading of dental implants. It begins with introducing immediate loading and defining related terms like immediate restoration, non-functional early restoration, and early occlusal loading. It then covers indications and contraindications for immediate loading, as well as advantages and disadvantages. The rationale for immediate loading is discussed, focusing on reducing surgical trauma and promoting bone remodeling. Factors that can decrease risks of immediate loading like implant number, size, design, and surface area are also outlined.
This document discusses terminology and techniques for dental implant impressions. It defines terms like cover screws, healing caps, transfer copings, and implant analogues. It explains that impressions are needed to capture the implant position, depth, axis, and soft tissue contour. The document outlines two main impression techniques - open tray (using pick-up copings) and closed tray (using transfer copings). It notes the advantages and disadvantages of each technique. Abutment level impressions are also discussed for customization and laboratory abutment selection. Gingival simulation is described as a technique to simulate the soft tissue around implants.

This document discusses the use of short implants for treating atrophic maxillae. It defines short implants as those less than 7mm in length and notes they offer advantages over traditional longer implants including requiring only a single surgery, shorter recovery time, and lower costs. The document presents two case studies where short implants were successfully used to treat bone resorption in the maxilla, with outcomes comparable to traditional longer implants. It concludes that short implants can yield results similar to conventional implants when the bone bed is properly prepared and splinted implants with canine guidance are used.

Immediate dental implants provide several advantages over delayed implants. An immediate implant is placed directly into the extraction socket at the time of tooth removal. This summary outlines guidelines for immediate implant placement including patient selection criteria, surgical technique, and post-operative follow up. A case report details the successful placement of an immediate implant to replace an infected tooth. Results at one year found excellent osseointegration and minimal changes to the soft and hard tissues with no signs of infection or peri-implantitis. Immediate implants can reduce treatment time and discomfort for the patient while achieving functional and aesthetic restoration in a single visit.
This study evaluated factors influencing the survival and success rates of 30 dental implants placed in 20 patients over a period of 6 months to 1 year. The results showed a 100% survival rate for the implants, with all implants meeting the criteria for implant health and success. Marginal bone loss was found between implant placement and 6 months post-placement, but no significant additional bone loss after 6 months. Patient and implant factors like bone quality, torque values, and implant design and dimensions did not significantly influence crestal bone loss. The implants were considered to be highly successful based on established criteria.
This study evaluated factors influencing the survival and success rates of 30 dental implants placed in 20 patients over a period of 6 months. The implants had a 100% survival rate and were deemed successful according to established criteria. Marginal bone loss was found between implant placement and cementation but not between cementation and the 6-month follow up. Patient and implant factors like bone quality, torque values, and implant design were found to minimize crestal bone loss and overall implant failure rates. Larger studies over longer periods are needed to obtain more consistent long-term data.

Immediate Implants Placed Into Infected Sockets: Clinical Update with 3-Year ...Abu-Hussein Muhamad
Dental implants can be placed immediately into healthy extraction sites with high success and survival rates. It has been suggested, however, that immediate placement of implants into infected extraction sites is contraindicated due to the pathology interfering with osseointegration resulting in decreased implant survival and success With many potential implant sites presenting with a preexisting periapical or periodontal infection, treatment protocols have been advocated for immediate placement of implants in these infected sites. Advancements in surgical techniques and implant surface technology have made immediate placement of implants a more predictable and accepted treatment option; however, there is still debate about whether infected extraction sites should be used for immediate implant treatment approaches. The purpose of this clinical update is to report on the success and survival of implants placed immediately into infected extraction sites.
This case report describes the immediate placement of a dental implant into a fresh extraction socket. A 53-year-old patient had a fractured maxillary lateral incisor extracted. The socket was prepared and a dental implant was immediately placed. Four months later, an impression was taken and a definitive crown placed. The patient exhibited no clinical or radiographic complications over two years of follow-up. Immediate implant placement and provisionalization preserved the hard and soft tissues and provided the patient with immediate aesthetics, function, and comfort.
The document discusses immediate implant placement and restoration in the anterior maxilla. It notes that while survival rates of immediate implants are high, there is usually loss of buccal bone and soft tissue recession over time. Immediate provisional restoration of implants can help preserve the buccal bone and soft tissues. For best outcomes with immediate anterior implants, the patient should have adequate bone volume and thick soft tissues.

Immediate dental implants are an attractive option to patients and dentists. This paper report the management of a
fractured right permanent maxillary central incisor with extraction of the root followed by immediate implant placement
with two years follow-up.
Over the past 50 years, dental implants have become a highly predictable treatment for replacing missing teeth, with success rates above 95% according to numerous 10-year studies. The field began in the 1960s with experiments by Branemark and Schroeder. Guidelines were established by the 1980s, and major progress was made between 1985-2000 in areas like aesthetics, bone augmentation, and surface technology. From 2000-2010 the focus was on fine-tuning protocols for improved aesthetics and 3D planning. Current trends examine challenges like peri-implantitis and new techniques like guided surgery and CAD CAM.

Abstract: Severe atrophy of the inferior alveolar process and underlying basal bone often results in problems with a lower denture. These problems include insufficient retention of the lower denture, intolerance to loading by the mucosa, pain, difficulties with eating and speech, loss of soft-tissue support, and altered facial appearance. These problems are a challenge for the prosthodontist and surgeon. In this case report, patient with resorbed edentulous mandible was successfully rehabilitated using two dental implants placed in the interforaminal region with ball abutments opposing conventional maxillary complete denture. Key Words: dental implants; dental prosthesis, implant-supported; resorption,
IMMEDIATE IMPLANT PLACEMENT WITH ONE YEAR FOLLOW-UP: A CASE REPORTAbu-Hussein Muhamad
This case report describes the immediate placement of a dental implant into the extraction socket of a fractured maxillary central incisor tooth. The tooth was extracted atraumatically without flap reflection. A dental implant was immediately placed into the prepared socket and achieved primary stability. A provisional restoration was placed on the same day. Follow up over 12 months showed good osseointegration of the implant with no clinical or radiographic complications. Immediate implant placement and provisionalization can preserve alveolar bone and soft tissues while providing immediate esthetics and function.

The document summarizes the results of several randomized controlled trials that compared different dental implant systems. The trials evaluated outcomes such as implant failure rates, marginal bone loss, and peri-implant tissue health. The studies generally found no statistically significant differences between major implant systems from companies like Straumann, Nobel Biocare, 3i, and others for factors like failure rates or bone loss over periods of up to 5 years.
The document summarizes findings from 10 randomized controlled trials comparing different dental implant systems. The trials evaluated outcomes like failure rates, marginal bone loss, and peri-implant soft tissue health. Meta-analyses found no significant differences between systems in failures or bone loss over time, including between surface types. Subsequent follow-ups of initial trials continued finding no significant differences in long-term outcomes between major implant systems.

This document summarizes a case report of a patient with a severely resorbed edentulous mandible who was successfully rehabilitated with two dental implants placed in the interforaminal region with ball attachments supporting an overdenture. After 10 years of follow-up, the patient was highly satisfied with the retention, comfort and function provided by the implant-retained overdenture. The case report also reviews literature on the use of implant-supported overdentures for treating resorbed edentulous ridges, finding they provide better function and retention compared to conventional dentures and reduce further bone loss.
This document reviews the evolution of external and internal implant-abutment connections. It begins by discussing Brånemark's original external hexagonal connection and limitations. It then describes modifications to the external hexagon connection including tapered hexagons, external octagons, and spline connections. Finally, it discusses the development of internal connections to overcome issues with external connections and improve stability, including early designs like the Core-Vent implant. The goal is to provide an overview of different connection types that have been developed.

89. Tilted Implants Literature Review Tilted implants are a safe and effective treatment that has many benefits for the patient
90.
91. Added components Smaller screws Added modes of failure Increased cost Increased time Large Screw Retained Restorations
92. 2 mm minimum distance To correct angle More time and cost than going direct to implant Potential aesthetic problems Angle corrected abutments often require tabling of bone Templates for lab to mouth
93.
94.
95. Anatomy and/or bone loss often lead to less than ideal implant location in the maxillary anterior making their restoration difficult Problem:
96.
97.
98. Co-Axis Implant Development It was determined by digital photographic analysis and cephalometric evaluation that an angle correction of 12 degrees would allow for vast majority of maxillary anterior implant restorations to be screw retained Edentulous areas
99. C. Nikolopoulos, Oral Surgeon P. Youvanoglou, Pros. G. Ioannou, Technican Co-Axis Implant No intermediate abutments No tabling bone
100. Co-Axis 24 º External hex with slightly shorter screws and healing components
103. The Co-Axis Implant Co-Axis implant may be placed into available bone while leaving the restorative platform in an optimal position Use Co-Axis implants in locations where conventional implants would require a bone graft or result in the inability to easily or adequately restore the implant Correct angle in implant, not the restoration
104. Co-Axis Implant Instrumentation 12 degree direction indicator (after twist) 12 degree direction indicator (after final shaping) in 10, 13 and 15mm
109. Is It Strong Enough With That Thin Wall? Straight Implant Co-axis Implant Same amount of titanium just more on one side than other
110. Finite element analysis 3.75 mm Implant Ext. Hex 350N load at 22° to long axis 350N load at 22° to long axis Finite element analysis Co-Axis 12 degree Finite Element Analysis
118. 10 degrees More vertical placement of implants Under contouring of restoration Narrower healing caps Platform switching Immediate restoration Increase amount of tissue
119. Vertical Placement of Implants In Anterior Maxilla Anatomy of the anterior maxilla often results in facially inclined implants that leads to long teeth
120. In same osteotomy site a Co-Axis implant will result in more mid-facial soft tissue than a straight implant
121. “ Need my crown recemented” Emergency immediate restoration
131. The Co-Axis implant has two distinct axes to allow easier replication of the two planes nature gave maxillary anterior teeth

Editor's Notes
Southern has all these studies available upon request
Rct’s
Southern Philosophy. If only one best for you and patients than so be it
Benefit not first, not last
Take good idea and make it better
Nobel’s Select internal connection had been around about 5 yeas
Strength testing thicker wall tri lobe minimize flowering fracture or distorts top tri-lobe area ,or late fractures
Along w/ thicker tri lobe wall section helps fatigue added internal hex to minimize forces that may flower or distort top tri-lobe area
Smaller polished collar + micro-groves
Originally when Nobel developed immediate load experimental
lots of small changes that make it better for some cases,
Literature available form Southern
Just because unique doesn’t mean it’s a good thing, must not sacrifice quality
If not do one or more of above why??? Southern unique products , immediate placement
Shortens treatment time, more efficient, but molars lost more often in adults
Where the profile is strait or slightly tapered
Delayed placement is inefficient
Problem not as efficient as single rooted
Look at size of sockets 6, 6.5,. Or even 7mm usually too small
over 2 years of trials and 3 modifications developed the following history interesting, not time
Available in all 3 connections, use wide connectors
Location of self tapping flutes, lengths of 7mm, 9mm, 11mm
Round bur
Twist drills, 2 and 3mm
Large tapered drills work up depending on density and amount of bone
Notice so far same burs as for other impants
Final dedicated tapered drill
Insert impant
Countersink. 2 by 2 rule
Red arrows show all 4 walls have contact w/ implant and yellow arrow shows no contact, suture over need graft material to stop down growth or as is. 2 by 2 rule
Tarnow at AO, if not suture over site leave space clot, some graft other do not, very experienced users think depth of placement more important than graft
Hard to pull, leaves more attached tissue. Most do not suture
Note inter-proximal countersink again
voerman
Beyond the drills this tap/drill excellent for controlTap also drills some
Soft bone, single roots second molars, small sinus communications no big thing
Instruments are same for placement of any implant except for the final instrument before placement which is one of three
Implants are actually undersized for sockets, history of wides
Single implant into mesial or distal root
Exposed threads, not deep enough or inadequate or damaged buccal plate
Osteotome, six indentations
Dr. Graves, submitting article w/ 160 ?, and my numbers. Over 300 w/ about 94%?
60% to 80%
Another unique implant , allows me to be more efficient w/o sacrificing quality, larger cases and less likely scenario
12 degree 4mm external hex and 24 degree external hex use shorter screws, rest compatible
One optimal position, 0.6mm tread pitch
All three connections on 12 degree
Note internal hex is where insertion tool engages implant, minimize distortion or fracturing, more efficient
As with MAX more efficient for me , discuss large cases first, smaller next larger cases, full arch, want screw retained
I did literature review Southern has my literature review available and part referenced in Co-Axis article
48 articles up to 15 years follow up
Works, less time and cost, maxillary sinus, mandibular nerve
Co-Axis takes access opening to the lingual, Fermit, light cured temporary , this how started in early 1990’s
With tooth and if bone loss significant
2 24 degree in posteriors and 4 12 degrees in anterior
Surgeon gets his bone, restorative dentist gets his desired platform position.
For me, Screw retained or cemented not discuss I do most efficient,, larger cases screw retained, bridge taper porcealin chipper
Makes using tilted implants easier for dentist and patients
3 exposed threads and 15mm?, anterior less stress on screw
FDA approval, most stringent to my knowledge. My experience 6 years
Implant higher interproximal like Nobelperfect or Innovas Anatomical implant, protottype
Problem single teeth, midfacial bone interproimal determined by bone on adjacent teeth
Dictated by anatomy, amount of bone
Theoretical, but does it happen
Everyday example
Surgical axis vs. prosthetic axis,
Believe secret to better esthetics in single teeth is:
The picture on R side shows what would be facial access opening of screw due to either bone loss before placement, angulation of facial plate relative to where clinical crown of natural tooth was, or poor surgical placement .
Anterior routinely done,
My conclusions about Coax and max with regard to what they do for my practice and my patients
