Mandibular alveolar ridge extension method using a surgical splint with porous hydroxyapatite (HAP) particles

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Severe resorption of the mandibular alveolar ridge presents challenges for dental prosthetic rehabilitation.
• Existing techniques may have limitations in achieving adequate ridge extension.
• A novel approach is needed to effectively augment the alveolar ridge.

Purpose of the Study:

• To describe and evaluate a surgical technique for mandibular alveolar ridge extension using porous hydroxyapatite (HAP) particles.
• To demonstrate the application of a custom surgical splint in conjunction with HAP for ridge augmentation.
• To establish a method for reconstructing severely resorbed mandibular alveolar ridges.

Main Methods:

• A surgical splint is fabricated on a remodeled working cast of the resorbed mandibular alveolar ridge.
• A subperiosteal tunnel is created, and the surgical splint is secured to the mandible.
• Porous hydroxyapatite (HAP) particles are injected into the subperiosteal tunnel for ridge extension.
• A treatment denture is constructed using the surgical splint and artificial dentition post-healing.

Main Results:

• The described technique allows for the extension of the mandibular alveolar ridge to meet clinical requirements.
• Porous hydroxyapatite (HAP) particles facilitate the augmentation process within the subperiosteal tunnel.
• The surgical splint guides the placement and containment of HAP particles for predictable outcomes.

Conclusions:

• The mandibular alveolar ridge extension method using porous hydroxyapatite (HAP) particles and a surgical splint is a viable surgical technique.
• This method effectively addresses severe alveolar ridge resorption, enabling better prosthetic outcomes.
• Further clinical studies may be warranted to assess long-term efficacy and patient satisfaction.
