ASTM F-75 Cobalt-base alloy castings are widely used for manufacturing orthopedic implants. This alloy needs both homogenization and solutionizing heat treatment after casting, as well as bioactivation of the surface to increase the ability of tissue bonding. In this study, ASTM F-75 Cobalt-base substrate was heat treated at 1220°C for 1 hour in contact with Hydroxyapatite-Bioglass powder in or...

Breast reconstruction is an important procedure for women who have had a mastectomy due to breast cancer or other diseases. can improve self-esteem, body image, and quality of life experienced loss. with implants effective popular technique after mastectomy. However, it also has its limitations complications, so patients surgeons work together select the right minimize risk post-operative compl...

It is the responsibility of the restorative dentist to fabricate a surgical guide that dictates to the surgeon exact placement of each implant. Misaligned implants complicate the clinical and laboratory procedures in the fabrication of definitive restorations. The nonparallel placement of implants, especially when multiple implants are placed, can cause nonaxial loading during function, which m...

From the earliest attempts to successfully design and place dental implants, immediate loading and function have been hallmarks of treatment. Abundant failures in the early developmental stages of implants were commonplace and often occurred immediately or after a short period of functional loading. In many cases, patients were left with clinical problems more severe than their original edentul...

Anchorage has been defined as a resistance to unwanted tooth movement. It is imperative for the treatment of both dental and skeletal malocclusions. Skeletal anchorage provides better chances obtain absolute in orthodontic The topic vast compiling it one single article will be an injustice readers. So, we have divided this into two review articles under headings introduction, evolution historic...

Osseointegrated dental implants seem to be applicable for anchoring orbital prostheses in cases of previous extended ablative surgery of the orbit including excenteration of an eye. These implants are applied at stage one and connected with abutments at stage two of a two-stage surgical procedure. Nine Caucasian patients with a total of 25 osseointegrated periorbital dental implants were studie...

The zygomatic implant is an alternative to bone grafting in extremely resorbed maxilla. This study evaluates the results of a consecutive cohort of 20 patients (mean age 56 years) with extremely resorbed maxillas provided with four zygomatic implants. The first 10 patients had a two-stage procedure, the next 10 next patients benefited from a one-stage surgical procedure and one of them had flap...

BACKGROUND Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. PATIENTS AND METHODS Seventy patients with complete mandibular edentulism underwent ...

Numerous authors have documented clinical success in loading threaded implants at the time of implant placement when carefully controlled surgical and restorative protocols are followed. This clinical series documents the application of immediate loading techniques to fixed mandibular restorations in 27 patients who were edentulous or had non-restorable mandibular dentitions. Eighteen patients ...
