A Retrospective Study of Bone-Level Stability Around 335 Hybrid Implants Placed with an Immediate or Delayed Protocol.

This retrospective study evaluated 335 hybrid implants placed in edentulous ridges; 167 were placed with an immediate implant protocol (IIP) and 168 were placed with a delayed implant protocol. Radiographic bone level changes were measured 1 to 23 years after loading. The average bone loss between implant placement and second-stage loading was 0.

A Retrospective Study of Bone Level Stability Around 441 Mandibular and 350 Maxillary Molar Implants Placed with an Immediate Implant Protocol.

The purpose of this retrospective study was to evaluate bone level stability around 441 mandibular and 350 maxillary molar implants, placed using an immediate implant protocol, that had been in function from 2 to 17 years postrestoration (mean: 9.9 years). Independent radiographic measurements using the known distance between threads on the specific implant that was used indicated a mean bone loss of 0.

Long-Term Bone Stability around 312 Rough-Surfaced Immediately Placed Implants with 2-12-Year Follow-Up.

Purpose: The purpose of this study was to retrospectively evaluate bone stability around implants with anodic oxidized surfaces and correlate this with variables compared in a previous study.

Materials And Methods: A total of 312 implants with anodic oxidized surfaces were separated from a pool of 1,187 implants placed immediately following tooth extraction. Radiographs made at the time of implant placement were compared to radiographs taken at 2-12 years' follow-up.

Long-term bone stability assessment around 1,187 immediately placed implants with 1- to 22-year follow-up.

Purpose: To evaluate the retention of bone around implants placed immediately following tooth extraction and used to support dental prostheses.

Materials And Methods: Patients from a previous study of implants placed immediately following tooth extraction were recalled to the original practice to obtain dental radiographs, which were then used to compare bone levels after 1 to 22 years of clinical function supporting dental prostheses. All radiographs were evaluated by measuring the bone within the implant threads.

Prospective study of 94 platform-switched implants observed from 1992 to 2006.

The purpose of the present prospective study was to evaluate implant survival and crestal bone levels around implants that used the platform-switching concept and were followed for a minimum of 11 years. Radiographs of 94 implants obtained 11 to 14 years after loading were evaluated by measuring the location of the crestal bone level relative to the implant platform. All implants had been placed at the crestal level at the time of surgery.

Immediate provisionalization of NanoTite implants in support of single-tooth and unilateral restorations: one-year interim report of a prospective, multicenter study.

Background: Clinical studies reporting immediate loading of endosseous implants for edentulous cases and for fixed partial restorations have been well documented with satisfactory survival rates. Implants with a recently developed, nanometer-scale surface topography (NanoTite, BIOMET 3i, Palm Beach Gardens, FL, USA), created by discrete crystalline depositions (DCD) of calcium phosphate nano-crystals onto a dual acid-etched (DAE) surface, show enhanced early fixation in preclinical studies when compared with DAE-surfaced implants. These outcomes suggest DCD-surfaced implants may be advantageous for immediate loading approaches.

A retrospective study of 1925 consecutively placed immediate implants from 1988 to 2004.

Purpose: The purpose of the present study was to evaluate implant survival rates with immediate implant placement (IIP) into fresh extraction sockets and to determine risk factors for implant failure.

Materials And Methods: A retrospective chart review was conducted of all patients in whom IIP was performed between January 1988 and December 31, 2004. Treatment required atraumatic tooth extraction, IIP, and mineralized freeze-dried bone allograft with an absorbable barrier to cover exposed implant threads.

A study of the fate of the buccal wall of extraction sockets of teeth with prominent roots.

The objective of this investigation was to determine the fate of thin buccal bone encasing the prominent roots of maxillary anterior teeth following extraction. Resorption of the buccal plate compromises the morphology of the localized edentulous ridge and makes it challenging to place an implant in the optimal position for prosthetic restoration. In addition, the use of Bio-Oss as a bone filler to maintain the form of the edentulous ridge was evaluated.

Considerations in treatment planning of the periodontal patient.

Through the use of periodontal, orthodontic, and restorative procedures, this patient was restored to function with a stable dentition and minimal pocket depths. The patient was followed for 10 years. All areas exhibited a healthy periodontium with stability of all areas of the dentition.

Immediate implant placement on removal of the natural tooth: retrospective analysis of 1,081 implants.

Conventional implant therapy dictates a period of 1 to 2 years from the start of treatment to the completion of the restoration. In contrast, immediate implant placement has resulted in the initiation of prosthetic treatment in as little as 3 to 6 months with the additional benefit of reducing alveolar bone resorption, patient morbidity, and expense. This article reports on the criteria for immediate implant placement into an extraction socket, as well as a reliable technique and a retrospective analysis of 1,081 implants placed immediately into extraction sockets.

Therapy for a patient with oligodontia: case report.

Oligodontia, the congenital absence of numerous teeth, presents many problems for both patient and therapist. Chief among these is the sequence and timing of orthodontic therapy, implant placement, and restorative dentistry. The absence of teeth can pose not only functional but psychosocial problems for young people.

A multidisciplinary approach to the treatment of oligodontia: case report.

The treatment of young people with implants requires advanced planning and coordination of many different specialities within dentistry. Timing and sequence of therapy will often decide the success or failure of treatment. Congenital absence of many teeth (oligodontia) associated with or without syndromes poses not only functional but also psychosocial problems for young people.

The diagnosis and management of vertical defects within the furcation.

This article describes two common varieties of osseous lesions within the furcation--hemifurcal and crescent-intrafurcal defects--and their appropriate management. Although hemifurcal lesions are difficult to assess both radiographically and clinically, once they are diagnosed, they can be readily resolvable using a self-regeneration procedure or an osseous graft. Crescent-intrafurcal defects are more common than hemifurcal lesions and can be discerned more easily on radiographs than clinically.

The role of orthodontics in periodontics and restorative dentistry.

Uprighting and extrusion are two movements that are used to aid in the treatment of difficult periodontal and restorative problems. Simple appliances can be used to alter tooth position, enhancing either the periodontal therapy, restorative dentistry, or both. Treatment time can be limited to 3 to 6 months.

Achieving ideal esthetics in osseointegrated prostheses. Part II. The single unit.

There are several advantages to the CeraOne single-tooth abutment. It seats directly onto the fixture, forming a nonrotating joint. A new type of gold alloy screw that can be tightened to 32 N/cm is used.

Periodontal preparation of the adult patient prior to orthodontics.

Evaluation of periodontal status and proposed orthodontic therapy must be made prior to initiating tooth movement. Teeth with a compromised periodontium can be treated. Prior to initiation of orthodontic therapy, it may be necessary to perform periodontal surgery for pocket elimination or reduction, to perform mucogingival surgery, or to correct gross occlusal discrepancies.

The analgesic efficacy of suprofen in periodontal and oral surgical pain.

Suprofen is a new, orally effective nonsteroidal antiinflammatory analgesic of the propionic acid chemical class. Three separate single-dose studies were performed to evaluate the efficacy of suprofen in acute pain associated with periodontal surgery and removal of impacted third molars. Study medications were: A--suprofen 200 mg, codeine 60 mg, propoxyphene HCl 65 mg, and placebo; B--suprofen 400 mg and 200 mg, aspirin 650 mg, and placebo; C--suprofen 400 mg and 200 mg, aspirin 650 mg with codeine 60 mg, aspirin 650 mg alone, and placebo.
