Официальное название

Radiographic Evaluation of Crestal Bone Changes Around Implants in Patients Treated With Delayed Loaded All on Four (Randomized Clinical Trail)

Обзор

The Goal of the clinical trail is to evaluate the Bone height changes around two axially placed anterior implants and two distally inclined 30-degree angle posterior implants in comparison to two axially placed anterior implants and two distally inclined 45-degree angle posterior implants using cone beam CT (CBCT). Patients will visit the clinic after the surgery and after the framework and denture insertion for check ups and during the follow up periods ( at denture insertion, 6 months and 12 months)

Подробное описание

All patients will receive upper complete dentures and mandibular All on-4 screw-retained prosthesis. The upper complete denture will be mucosa supported and the lower will be All on-4 screw-retained prosthesis. Patients will be divided into two equal groups; Group I will receive two axially placed anterior implants and two distally inclined 30-degree angle posterior implants, while Group II will receive two axially placed anterior implants and two distally inclined 45-degree angle posterior implants.

Both groups will be functionally loaded after three months of insertion. Bone height changes around axial and distally inclined implants will be evaluated using cone beam CT (CBCT), All records will be taken at time of denture insertion, 6 and 12 months later.
