Implant treatment planning: endodontic considerations.

Implants are a predictable and effective method for replacing missing teeth. Some clinicians have advocated extraction and replacement of compromised but treatable teeth on the assumption that implants will outperform endodontically and/or periodontally treated teeth. However, evidence shows that conventional therapy is as effective as implant treatment.

Review of models for titanium as a foreign body.

A growing number of theories has evolved attempting to explain the process of dental implant failure. Titanium implants utilized outside of the mouth have exhibited breakdown through a foreign body reaction. Phenomena occurring in the body, such as passive dissolution, osteolysis and metallosis, have not been discussed relative to dental implants.

Periodontopathogen and Epstein-Barr virus-associated periapical periodontitis may be the source of retrograde infectious peri-implantitis.

Background: Herpesviral-bacterial synergism may play a role in periodontitis and peri-implantitis etiopathogenesis. Periapical periodontitis (PP) lesions can predict future apical peri-implantitis complications.

Purpose: This pilot study aimed to substantiate herpesviral-bacterial coinfection in symptomatic (SP) and asymptomatic (AP) PP and assess associations with periodontopathogen salivary contamination in patients receiving implants.

Computer-aided design evaluation of harvestable mandibular bone volume: a clinical and tomographic human study.

Purpose: To evaluate and compare the volume of bone graft material that can be safely harvested from the mandibular symphysis and rami using a computer-aided design (CAD) software program.

Materials And Methods: Preoperative computerized tomography scans from 40 patients undergoing bone augmentation procedures were analyzed. Symphysis and rami cross sections were mapped using a CAD software program (AutoCAD(®), Autodesk, Inc.

Dynamic therapeutic approach for individuals affected with aggressive periodontitis.

Management of patients affected with aggressive periodontitis is complicated by several poorly understood etiological and modifying factors that create difficulty in establishing a universal treatment recommendation. The goal of this manuscript is to underscore the complexity of therapy and to provide some guidelines in the decision-making process and interdisciplinary therapy. A dynamic approach is presented to formulate strategies in diagnosis and treatment planning that is both patient-and site-specific.

Aggressive periodontitis: the historic quest for understanding.

Aggressive periodontitis has had many names as well as theories behind its etiology. The current paper looks to investigate this history and show the evolution of both nomenclature and understanding. Going beyond academic debates, emerging trends and conventions are also examined and placed into a clinical perspective.

Periodontopathogen and Epstein-Barr virus contamination affects transplanted bone volume in sinus augmentation.

Background: Bone microbial contamination can impair osteogenesis. Human herpesviruses-associated vasculitis can cause vascular damage within the osseous graft and host. This study is conducted to substantiate specific contamination and assess the impact 6 months after sinus augmentation.

Long-term block graft stability in thin periodontal biotype patients: a clinical and tomographic study.

Purpose: To assess the esthetic and functional outcome, as well as the volume maintenance, of autogenous block grafts placed in anterior sextants of thin periodontal biotype subjects over a long-term period.

Materials And Methods: Fifteen consecutive patients were followed up yearly for an average of 40 months after autogenous block grafting. Preoperative and postoperative cone beam computed tomographic scans were analyzed to evaluate bone volume maintenance around the implants placed in the grafted sites.

Human bone repair after mandibular symphysis block harvesting: a clinical and tomographic study.

Background: There are limited data on the healing potential of osseous defects in the human mandible. Animal model studies have shown that defect fill is size dependent.

Methods: Twenty patients who had autogenous block transplants harvested from the mandibular symphysis were included in the study.

Quantitation of mandibular ramus volume as a source of bone grafting.

Background: When alveolar atrophy impairs dental implant placement, ridge augmentation using mandibular ramus graft may be considered. In live patients, however, an accurate calculation of the amount of bone that can be safely harvested from the ramus has not been reported. The use of a software program to perform these calculations can aid in preventing surgical complications.

Periodontal biotype influence on the volume maintenance of onlay grafts.

Background: Autogenous osseous transplants have advantages, including the maintenance of bone density and high concentrations of growth factors. Little is known about the potential long-term influence of periodontal biotype on the volume maintenance of block grafts.

Methods: Forty patients who received autogenous block transplants prior to implant placement were included in the study.

Quantitation of mandibular symphysis volume as a source of bone grafting.

Background: Autogenous intramembranous bone graft present several advantages such as minimal resorption and high concentration of bone morphogenetic proteins. A method for measuring the amount of bone that can be harvested from the symphysis area has not been reported in real patients.

Purpose: The aim of the present study was to intrasurgically quantitate the volume of the symphysis bone graft that can be safely harvested in live patients and compare it with AutoCAD (version 16.

Immediate loading dental implants: overview and rationale.

Brånemark established the concept of osseointegrated dental implants as a predictable modality for treatment of edentulous patients. He defined osseointegration as bone-to-implant contact at the microscopic level. Osseointegration was a revolutionary concept in implant dentistry.
