Radiographic and Histomorphometric Assessment for Alveolar Ridge Preservation Using Autogenous Tooth Graft From Extracted Tooth Combined With Simvastatin 1:1 Versus Autogenous Tooth Graft

Radiographic and Histomorphometric Assessment for Alveolar Ridge Preservation Using Autogenous Tooth Graft From Extracted Tooth Combined With Simvastatin 1:1 Versus Autogenous Tooth Graft: A Randomized Clinical Trial (RCT)

This study will be held to overcome the previous limitations related to bone loss after teeth extraction by taking advantages from both Autogenous tooth graft and Simvastatin which will offer a promising synergistic approach for reducing alveolar ridge resorption, enhance bone regeneration and ensuring implant site development for future implant placement. This combination will address the gap in knowledge and offering a novel approach in alveolar ridge preservation. The Autogenous tooth graft will provide a scaffold and growth factor source for bone regeneration while Simvastatin will promotes osteogensis and angiogensis at graft site. So The goal of the present trial aims to evaluate the first-time application of Autogenous tooth graft from extracted tooth combined with Simvastatin with a ratio 1:1(test group) versus Autogenous tooth graft alone (control group) at an extraction socket of non molar single rooted teeth for alveolar ridge preservation and implant site development prior to implant placement.

The participants will be divided into two groups:

Intervention Group will receive Autogenous tooth graft combine with Simvastatin with a ratio 1:1 Control Group will receive Autogenous tooth graft. with follow up period 4 months.

Alveolar ridge resorption following tooth extraction is one of the greatest challenges in dentistry, especially for patients seeking dental implants. The alveolar ridge undergoes significant decrease in bone dimensions which will complicate the implant placement and thus necessitate additional grafting procedures to compensate the bone loss. Bone height decreases progressively by 25% during the first year after tooth loss, with a total of 4 mm of height lost during this first year post-extraction.

So various grafting materials such as Autogenous bone grafts, bone substitutes and allografts, are adopted to overcome this challenge and preserve the alveolar ridge. Autogenous grafts are always the gold standard and the benchmark of all graft types because of Its osteoinductive, osteoconductive, and osteogenic. However, secondary surgical sites, pain, high rates of donor site morbidity, and limited supply of graft material are the main disadvantages of autogenous graft.

Among these also, Autogenous tooth graft the promising solution due to its biocompatibility, osteogenic properties and nature compositions that mimics the structure and function of lost bone.

Autogenous tooth graft a type of autogenous grafting technique that utilizes the extracted tooth/teeth of the same individual for the preparation of the graft material. A relatively new and innovative bone graft material with all the advantages of autogenous bone owing to its very similar components to bone and can be very useful in a multitude of clinical situations.
