Vertical Versus Inclined Implant to Retain Locator Maxillary Overdenture

Not Applicable

Completed

• Conditions: Bone Loss; Implant Complication
• Interventions: Procedure: implants

• Registration Number: NCT05843331
• Lead Sponsor: Mansoura University

Brief Summary

Objectives: evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures. There were two groups : 1) The control group 2) The study group

Detailed Description

the aim of the present investigation was to evaluate the success rate, prosthetic maintenance , clinical and radiologic results of vertical implants with straight abutments versus inclined implants with angled abutments to retain locator maxillary overdentures.

Materials and Methods conducted on 12 patients (6 males and 6 females) aged 58 to 68 years with completely edentulous maxillary ridges opposing implant-retained mandibular overdentures. Patients admit to the prosthodontic department, Faculty of Dentistry, Mansoura University for oral rehabilitation by implant-supported maxillary prostheses. Patients were allocated into one of two treatment groups: 1) The control group ; included 6 patients (3 males and 3 females) who will receive 4 vertical implants with straight trans mucosal abutments retaining locator maxillary overdenture 2) The study group; include 6 patients (3 males and 3 females) who will receive 4 inclined implants with angled trans mucosal abutments for retaining locator maxillary overdenture. Randomization and allocation of patients into treatment groups was made by dental personnel who is blind to treatment groups.

Arm && Interventions

Group	Intervention	Description
posterior vertical implants	implants	the anterior implants were inserted in the canine/lateral incisor area bilaterally to each other's following the contour of the alveolar bone of the premaxilla. The posterior implants were inserted vertically just anterior to the maxillary sinus (in the area of second premolars) .
posterior inclined implants	implants	The anterior implants were inserted in the canine/lateral incisor area bilaterally to each other's and will be inclined 15o labially following the contour of the alveolar bone of the premaxilla. The posterior implants were inserted just anterior to the maxillary sinus (in the area of second premolars) and inclined 15o distally .

Primary Outcome Measures

Name	Time	Method
plaque index	12 months	measure plaque around each implant using Mombelli indices
pocket depth	12 months	dental probe used to measure the depth of formed pocket around each implant
implant stability	12 months	stability of each implant measured using Osstell® device

Secondary Outcome Measures

Name	Time	Method
Radiographic outcome	12 months	measuring bone resorption using the long-cone standardized periapical radiography
