Evaluation of Papilla Index Around Immediate Mandibular Molar Implants Using Customized Healing Abutment Versus Submerged Healing
Sponsor: Cairo University
Summary
The original implant treatment protocol recommended that the implant should be placed in a fully healed site and covered with mucosa after placement to ensure osseointegration. The reason was to protect the implant site from bacterial contamination and to avoid loading of the implant. After that, a second stage surgical procedure had to be performed to expose the implant to connect the abutment. However, it was shown that a one stage or non-submerged (NS) approach can lead to successful and predictable outcomes. Customized healing abutments can be used in the non-submerged protocol, protecting and containing the bone substitute during healing, preserving the alveolar contour, preventing food impaction, and eliminating the need for a second stage surgery and. By means of this technique, critical and subcritical contours can be projected speeding up the peri-implant soft tissue conditioning phase in order to achieve final natural-like restorations. This randomized controlled trial will compare the clinical and radiographic hard and soft tissue changes using chairside customized healing abutment versus submerged healing following immediate implant placement in mandibular molars through measuring the horizontal ridge changes by CBCT , the crestal bone loss by a standardized digital x-ray and the soft tissue changes by the pink esthetic score (PES).

Immediate molar implant with customized healing abutment
Patients will receive an immediate implant with customized healing abutment 1. Atraumatic extraction without flap elevation using periotomes and elevators then sectioning of the roots will be performed to preserve the interseptal bone. 2. The drilling will be performed starting from the pilot drill in the interseptal bone to the twisting drills according to the manufacturer's instructions to the selected implant size. The implant is to be placed immediately then the insertion torque will be measured using a torque wrench. In order to place the customized healing abutment, the insertion torque should be more than 25 ncm. 3. The gap distance will be filled by xenograft, a plastic abutment will be screwed in place then a flowable composie resin will be applied around into small amounts and cured to take the soft tissue contour then finishing and polishing of the customized healing abutment will be done.
