About

This study aims at assessing the hard and soft tissues remodelling of the alveolar crest after extraction socket managements in the aesthetic areas:

• 3D radiographic evaluation (CT scan) was performed post extraction and 3 months after at the time of implant placement. (Outcomes 1: Hard tissues analyses )
• Impressions, models and 3D analyses of the treated area allowed studying external soft tissue remodeling at different time points after extraction. (Outcomes 2: Soft tissues analyses )

Enrollment: 14 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients needing an extraction in the aesthetic area to be replace with an implant (incisive, canine or premolar)
• Good general health (ASA 1, 2)
• Controlled periodontitis
• No age restriction

Exclusion criteria

• Extraction socket with buccal bone defect / buccal bone wall dehiscence
• Smokers > 10 cigarettes per day
• Immune system disease
• Bone disease or treatment by medicines interfering with bone metabolism

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

Mucograft®, Geistlich Biomaterials

Experimental group

Description:

A Mucograft membrane will be used in state of a connective tissue graft. The dimension of the Mucograft® will be previously calculated according to the site dimensions and inserted into buccal pouch and sutured to be stabilized on the buccal aspect. The membrane is then positioned to cover the socket and inserted and sutured in the palatal pouch by the means of vertical interrupted sutures

Treatment:

Procedure: Socket preservation

Procedure: Test surgical protocol

Soft tissue graft

Active Comparator group

Treatment:

Procedure: Control surgical protocol

Procedure: Socket preservation
