Survival Rates of 8-mm or Shorter Tissue-Level Implants in Function for Up to 228 Months.

Purpose: Advances in surface technology and the understanding of the capabilities of osseointegrating implants have led to the use of shorter implants in a variety of clinical situations. Such implant use offers a number of potential advantages in the posterior maxilla and mandible. The purpose of this retrospective study was to examine the success rates of shorter, tissue-level implants in function for at least 60 months.

Success and Failure Rates of 1,344 6- to 9-mm-Length Rough-Surface Implants Placed at the Time of Transalveolar Sinus Elevations, Restored with Single Crowns, and Followed for 60 to 229 Months in Function.

Purpose: To assess the success and stability of 6-, 7-, 8-, and 9-mm-long, 6.5-mm-wide-neck tissue-level implants placed at the time of transalveolar sinus augmentation therapy, utilizing a trephine and osteotome approach, which were restored with single crowns.

Materials And Methods: In total, 1,344 implants were placed by the author, varying in length from 6 to 9 mm, with parallel-wall 4.

Complications when augmenting the posterior maxilla.

The maxillary posterior edentulous region presents a challenge when planning for restoring missing teeth with a dental implant. The available bone in such cases is often not dense and not adequate for the placement of a properly sized implant because of maxillary sinus pneumatization and alveolar bone loss. Maxillary sinus lift is a predictable procedure to provide adequate bone height for the purpose of implant placement.

Immediate implant placement in posterior areas: the mandibular arch.

When contemplating removal of a premolar or molar and its immediate replacement with an implant-supported prosthesis, the feasibility of other potentially less "aggressive" treatment approaches must first be considered. Treatment decisions must be made in the context of an appropriate definition of therapeutic success. Replacement of hopeless mandibular molars with implant restorations has undergone significant evolution since the introduction of osseointegrated implants some 30 years ago.

A retrospective analysis of immediately placed implants in 418 sites exhibiting periapical pathology: results and clinical considerations.

Purpose: While immediate implant placement has demonstrated a high degree of clinical success, questions remain about whether immediate placement of implants into sites demonstrating periapical pathology will result in treatment outcomes equivalent to those attained when implants are placed into sites that do not demonstrate periapical pathology.

Materials And Methods: A retrospective study was carried out of patients who presented with periapical pathology and were treated with tooth extraction, defect debridement, and immediate implant placement between 1994 and 2008. All immediately placed implants were followed for a minimum of 24 months after restoration.

A retrospective analysis of implants immediately placed in sites with and without periapical pathology in sixty-four patients.

Background: Many patients requiring implant therapy present with hopeless teeth exhibiting periapical pathology. The advisability of implant placement in such situations has not been conclusively determined.

Methods: Sixty-four patients underwent therapy in their maxillary incisor region.

Evidence-based decision making: replacement of the single missing tooth.

Single-tooth replacement may be effected through various methods, including the use of a resin-bonded fixed partial denture, a conventional fixed partial denture, and a single implant-supported crown. Although the introduction of newer therapeutic modalities, surgical and restorative techniques, and restorative materials has significantly expanded available treatment options, a greater demand is now placed on the diagnostic and treatment planning acumen of the clinician. The questions confronting each clinician are when to apply each treatment modality and how to use these therapeutic approaches to their maximum benefit for the patient.

Shorter implants in clinical practice: rationale and treatment results.

Introduction: The use of shorter implants offers a number of potential advantages if such utilization yields the same level of treatment success as the use of longer implants. The purpose of this retrospective study was to assess the survival of short implants in various clinical situations in function over time.

Materials And Methods: A retrospective study was conducted of all patients treated between May 2000 and May 2007 who received endosseous implants that were less than 10 mm in length.

Implant placement at the time of mandibular molar extraction: description of technique and preliminary results of 341 cases.

Background: Theoretically, the ability to place implants in ideal positions at the time of mandibular molar extraction with concomitant regenerative therapy would simplify and shorten the course of therapy for patients.

Methods: A total of 341 implants were placed in 320 individuals at the time of mandibular molar hemisection and extraction. Concomitant regenerative therapy was performed around 332 of the placed implants.

Implant placement at the time of maxillary molar extraction: treatment protocols and report of results.

Background: Implant placement at the time of maxillary molar extraction presents a number of potential benefits to patients. A technique to predictably attain implant placement in ideal positions was reported previously.

Methods: A total of 391 rough-surface implants were placed in 386 patients at the time of maxillary molar extraction.

Report of 1633 implants in 814 augmented sinus areas in function for up to 180 months.

Purpose: The long-term success of implants functioning in sinuses augmented with a variety of materials were evaluated in 2 private practices.

Materials: Treatment outcomes of 1814 augmented sinuses, and subsequent placement of 1633 implants into 763 augmented sinuses, were assessed through clinical and radiographic examinations in 2 private practices. Statistical analysis was carried out utilizing the analysis of variance method and step-wise linear regression at P < 0.

Immediate implant therapy in clinical practice: single-tooth replacement.

Once viewed as an esoteric treatment option, implant therapy has demonstrated long-term predictability at least equal to that of more "conventional" treatment modalities. The continued evolution of implant surface technology and restorative options has made implant therapy the treatment modality of choice in many if not most, clinical situations. It is, therefore, only natural that the role of immediate implant therapy continues to expand.

Implant placement with or without simultaneous tooth extraction in patients taking oral bisphosphonates: postoperative healing, early follow-up, and the incidence of complications in two private practices.

Background: The development of bisphosphonate-associated osteonecrosis in patients with a history of intravenous bisphosphonate therapy is a significant cause of concern in clinical periodontal practice. The role of oral bisphosphonates in the development of bisphosphonate-associated osteonecrosis is less clear. This article documents the results of treatment of patients with a history of oral bisphosphonate therapy in two private periodontal practices.

Maintaining primary closure after guided bone regeneration procedures: introduction of a new flap design and preliminary results.

Background: Various flap designs have been proposed by numerous authors for the maintenance of passive primary soft tissue closures following guided bone regeneration (GBR) procedures. A previous publication by the present author documented the maintenance of passive soft tissue primary closures 96.1% of the time at least 6 months after GBR therapy in all areas of the mouth.
