Tapered, Double-Lead Threads Single Implants Placed in Fresh Extraction Sockets and Healed Sites of the Posterior Jaws: A Multicenter Randomized Controlled Trial with 1 to 3 Years of Follow-Up.

Purpose: To evaluate the survival, success, and complication rates of tapered double-lead threads single implants, placed in fresh extraction sockets and healed sites of the posterior jaws.

Methods: The enrolled patients were randomly divided into 2 groups: in the test group (TG), all implants were inserted at the time of tooth extraction; in the control group (CG), all implants were placed 3 months after extraction. The implants were followed for a period of 1 to 3 years after loading.

Relationship Between Primary Stability and Crestal Bone Loss of Implants Placed with High Insertion Torque: A 3-Year Prospective Study.

Purpose: Concerns have been expressed about the possibility of high insertion torque (IT) causing necrosis, impaired osseointegration, and crestal bone loss over time. The present study investigated the relationship between primary stability and implant success, including early and late maintenance of crestal bone levels.

Materials And Methods: Implants were placed in patients at three study centers.

Short implants with oxidized surface in posterior areas of atrophic jaws: 3- to 5-year results of a multicenter study.

Background: The loss of one or more teeth has always been a reason for bone resorption and it can lead to a condition of "alveolar atrophy" that could make implant rehabilitation difficult.

Purpose: The aim of this prospective study was to observe crestal bone loss and implant success of short implants with oxidized surfaces in patients with partially edentulous jaws after a 3- to 5-year follow-up.

Materials And Methods: Forty-six patients with single or partial edentulism were treated consecutively from 2006 to 2008 using 107 short implants with oxidized surfaces, which were restored with a single crown or a partial fixed denture.

Short threaded implants with an oxidized surface to restore posterior teeth: 1- to 3-year results of a prospective study.

Purpose: The aim of this multicenter prospective study was to provide data from a case series supporting the use of short dental implants with oxidized surfaces to treat partially edentulous patients.

Materials And Methods: The implants used had an oxidized surface, a tapered design, and a short length (8.5 mm or shorter).
