Osseointegration has been defined as “a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant”. However, titanium and its alloys cannot directly bond to living bone after being implanted into the body. The osseointegration of titanium dental implants is critically dependent on the implant surface properties. Various surface modificat...

The retrospective study was conducted to assess the dental implants that experienced failure. It was conducted at the dental clinic of the Aga Khan University Hospital, Karachi, and comprised record of dental implants from July 2010 to June 2015. Variables such as patient age, gender and systemic status, length and diameter of implants, bone grafting, type of definitive prosthesis (crown or bri...

OBJECTIVE Human retrieved implants with an intact bone-implant interface play a pivotal role in validating data obtained from in vitro studies and animal experiments. This study presents a histologic and histomorphometric analysis of peri-implant tissue reactions and of the bone-titanium interface in three machined and sandblasted dental implants retrieved after a 5-year loading period. METHO...

Functional dental rehabilitation of patients with ectodermal dysplasia (ED) still remains a challenge due to severe hypodontia and underdeveloped alveolar ridges that often preclude implant placement without surgical augmentation. Only few data about technique and timing of augmentation and implant placement can be found in the literature. We have established a surgical algorithm as part of a f...

PURPOSE Much attention has been focused on the immediate or early loading of implants with or without splinting. The purpose of this study was to evaluate the contact rate between bones and implants, with or without splinting. MATERIALS AND METHODS Under general anesthesia, an 8-mm-deep cavity for a dental implant was drilled in the mandibular ridge of dogs where teeth had been extracted 4 mo...

STATEMENT OF PROBLEM The need for tooth replacement in individuals with Down syndrome (DS) is explained by the high prevalence of dental agenesis and by the premature loss of teeth through severe periodontal disease. Dental implants may be the dental procedure of choice in some of these patients. PURPOSE The purpose of this clinical study was to analyze dental implant survival in a series of ...

Purpose: To evaluate long-term clinical performance of 1-stage dental implant prostheses at a single clinic, emphasizing clinical and demographic characteristics that affect implant survival. Materials and Methods: Dental records of all 308 patients (674 implants) treated with 1-stage implants at Mayo Clinic from October 1993 through May 2000 were reviewed from implant placement to last visit. ...

background and aims. because of compromised angulations of implants, the abutments are sometimes prepared. the purpose of this study was to investigate the effect of removing one wall of the implant abutment on the retention of cement-retained crowns. materials and methods. four prefabricated abutments were attached to analogues and embedded in acrylic resin blocks. the first abutment was left ...
