Survival rates from placement to 36 months were reported for the ongoing Dental Implant Clinical Research Group studies of root-form endosseous dental implants. Failure rates for all implants were similar in bone qualities 1 and 2 (6.2% and 6.7%, respectively) and slightly higher in bone qualities 3 and 4 (8.5% and 8.7%, respectively). Hydroxyapatite(More)
Many of the presently used methods of evaluating osseointegration at implant uncovering are highly subjective. The Periotest is claimed to offer a more objective means to assess osseointegration by means of microcomputer-controlled percussion. Investigators involved in a long-term clinical study of dental implants being conducted by the Dental Implant(More)
Periotest values (Periotest, Siemens AG, Bensheim, Germany) were recorded as a baseline variable at surgical uncovering in the ongoing multicenter, prospective clinical studies of the Dental Implant Clinical Research Group, which uses implants from the Spectra-System (Core-Vent Corporation, Las Vegas, NV). For 2,212 osseointegrated implants, the mean(More)
The quality of bone plays an important role in the long-term clinical success of dental implant treatment. An interim evaluation of the relationship between bone quality and the incidence of failure at second-stage surgery is presented. The data include 2,131 root form implants placed by the Dental Implant Clinical Research Group over the past three years.(More)
BACKGROUND Although most patients with implants have lost their natural teeth because of poor oral hygiene, limited data exist to guide practitioners in their recommendations of home-care regimens for their patients' endosseous dental implants and maintenance of peri-implant soft-tissue health. The authors conducted a study to compare the home-care(More)
The prevalence of partial and complete edentulism in the older adult patient and the predictability of specific types of dental implants obligates the dental health professional to consider the fabrication of implant-related prostheses as an alternative treatment option. Special emphasis is placed in this article on the provision of clip-bat overdentures in(More)
Knowledge of the distribution of bone quality in the various jaw regions assists the clinician in dental implant treatment planning. Bone quality was assessed with radiographs and tactile sensation for 2,839 implants at the time of placement into four anatomic regions of the jaw. The Lekholm-Zarb classification system was used. Overall, bone quality types 1(More)
Radiographic follow-up of dental implants is one of the most important clinical parameters a practitioner can assess. Recent advances in the design of panoramic radiograph machines have increased their potential use in the longitudinal clinical evaluation of dental implants. Changes from the earliest designs allow for a projection geometry that more closely(More)
BACKGROUND Maintenance of the health and integrity of the bone-implant complex (osseointegration) has been shown to be essential for long term success of root-form, endosseous dental implants. If reliable clinical indicators of adequacy of the bone-implant complex existed, they could stimulate new and innovative early intervention research to arrest of(More)
Failure rates at second-stage surgery were reported for the ongoing Dental Implant Clinical Research Group studies of the Spectra-System (Core-Vent Corporation, Las Vegas, NV) implants. As of May 1995, 69 implants failed out of 2,633 placed and uncovered. The overall failure rate was 2.6%, with 3.6% in bone quality 1 (BQ-1), 2.4% in BQ-2, 2.5% in BQ-3, and(More)
