Pontic Shield and Mineralized Plasmatic Matrix for Ridge Preservation

Summary

This study is testing new methods to preserve the jawbone and gum tissue after removing a damaged front tooth. Normally, when a tooth is taken out, the bone and gums in that area shrink, which can make future dental treatment more difficult and affect appearance. A technique called Partial Extraction Therapy (Pontic Shield Technique) keeps part of the tooth root in place to help maintain the natural shape of the bone and gums. Another method, called Mineralized Plasmatic Matrix (MPM), uses a patient's own blood mixed with bone particles to support healing.

In this randomized clinical trial, 56 patients were assigned to one of four groups:

Group I: Tooth extraction only Group II: Tooth extraction with MPM grafting Group III: Pontic shield technique alone Group IV: Pontic shield technique with MPM grafting The main outcome measured was the amount of bone width preserved, using 3D X-rays (CBCT). Other outcomes included bone height and soft-tissue healing over 4 months.

This research will help determine whether the pontic shield technique, with or without MPM, provides better preservation of bone and gum tissue compared to tooth extraction alone.

Conditions

  • Alveolar Ridge Preservation

Interventions

PROCEDURE

Tooth Extraction only

Conventional atraumatic extraction of the non-restorable maxillary tooth in the esthetic zone without socket preservation procedures.

PROCEDURE

Extraction + MPM

Tooth extraction followed by socket grafting using MPM, prepared from autologous blood combined with xenograft bone particles.

PROCEDURE

Pontic Shield Only

Partial extraction therapy using the pontic shield technique, in which the buccal root fragment is preserved to maintain ridge contour, without additional grafting.

PROCEDURE

Pontic Shield + MPM

Pontic shield technique combined with grafting using mineralized plasmatic matrix (MPM) for enhanced ridge preservation and healing.
