Submerged Versus Non-Submerged Healing of Implants Subjected To Contour Augmentation

Submerged Versus Non-Submerged Healing of Implants Subjected to Contour Augmentation.

It is a randomized controlled trial to evaluate two surgical techniques for dental implant placement simultaneously with bone augmentation.

Study Overview

• Status: Completed
• Conditions: Tooth Loss
• Intervention / Treatment: Procedure: Transmucosal Technique; Procedure: Submerged Technique

Detailed Description

Implants receiving Contour Augmentations at the time of placement are randomized into two groups, submerged and non submerged. Healing is evaluated at 4 months post op compared to the day of surgery.

• Study Type: Interventional
• Enrollment (Actual): 28
• Phase: Not Applicable

Number of Arms

2

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Transmucosal (Non-Submerged); Flaps will be adapted to the healing abutments for a trans-mucosal healing up on closure	Procedure: Transmucosal Technique; Dental implant will be placed in transmucosal manner (Healing abutment is exposed in the mouth).; Other Names: Non-submerged technique
Active Comparator: Submerged; Flaps will be advanced to achieve primary wound closure.	Procedure: Submerged Technique; Dental implant will be installed in submerged manner (implant is completed covered by soft tissue).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Hard tissue healing around dental implants	bone healing around Submerged and Non-submerged dental implants will be measured by Periodontal probe and radiographs. A Mann-Whitney U Test will be used to calculate bone healing changes. To evaluate bone healing Mean values, standard deviations and frequencies will be calculated.	4 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Soft tissue healing around dental implants	Soft tissue healing around Submerged and Non-submerged dental implants. Fisher's exact test will be used to evaluate soft tissue healing changes through analyzing the measurements obtained by periodontal probe and radiographs.	4 months
