Standard extraction setup with added instruments to aid in bone contouring History of the Procedure The historical use for alveoplasty was to create a smooth and wide denture base.

This shape provides optimal stability to the removable prosthesis. In Willard described contouring of the alveolar bone and contouring of the alveolar mucosa to obtain primary closure in preparation for denture placement. He stated that this should allow the patient to be restored sooner because the bone and tissue healed faster.

In Beers described radical alveolectomy with cutting forceps. This was aggressive treatment, and clinicians reverted to being more conservative over the next 50 years. The procedure was not looked on favorably because the bone underwent a tremendous amount of bone loss after the surgery. The bone loss was thought to be due to the periosteal stripping and large flaps developed to provide access for the bone contouring surgery.

In Molt recommended using models to plan the reshaping of the bone. His idea was to preserve bone and to maintain an appropriate vestibule.

In Dean described his technique to preserve the labial cortex and contoured intraradicular bone. This allowed him to compress the labial plate. No mucoperiosteal dissection leads to less pain, swelling, and bone resorption. In Michael and Barsoum studied patients who had immediate denture placement and the amount of resorption associated with different surgical techniques, such as extraction without alveoplasty, extraction with labial alveolectomy, and extraction with intraseptal alveoplasty as described by Dean.

The extractions alone had the least amount of bone loss; the labial alveoplasty had the most, even after 12 months. The advent of implant dentistry has turned the table. Now, contemporary therapy focuses on maintaining as much bone as possible to facilitate implant placement. Moreover, augmenting the alveolus for rehabilitation purposes is fairly standard procedure. History of the Procedure The historical use for alveoplasty was to create a smooth and wide denture base.

Indications for the Use of the Procedure Reshaping of the alveolar bone has multiple indications in maxillofacial surgery. All techniques used provide resurfacing or restructuring of the alveolar bone to provide a functional skeletal relationship.

The indications for alveoplasty range from debulking procedures for pathologic conditions of the bone to recontouring the bone in preparation for prosthetic rehabilitation.

Simple plasty of the alveolar bone is defined as the reshaping of the alveolar bone during dental extraction surgery. If the alveolus has a sharp edge, the bone must be smoothed down to help with the healing process and prevent sequestra formation and pain. The contouring of the alveolus after extractions also aids in prosthetic rehabilitation, whether with dental implants or dentures. Any sharp bone projections or edges under dentures create pain when the prosthesis compresses and rubs against them.

The shape of the ridges for denture fabrication should maintain as much width and adequate height as possible to distribute forces properly. Undercuts must be addressed to allow for smooth placement of the prosthesis. The goals are to lose as little bone as possible after extraction, to maintain a wide alveolar ridge with the ideal U shape, and to get rid of undercuts that prevent smooth use and placement of a removable prosthesis.

With respect to dental implant rehabilitation, the reshaping of the alveolus is done to provide a stable base to place the dental implants and to create enough room for the prosthetic components necessary to restore the dentition.

This may require removing some of the bone, which may be counterintuitive to the protocols for creating dentures. Limitations and Contraindications Alveoplasty is limited by the local architecture and volume of bone in the surgical site. It is contraindicated if removing the bone would harm vital structures.

It also is contraindicated if the patient does not need bone removed or recontoured. Compression of the Alveolar Ridges Compression is done after extractions when the labial, buccal, and lingual or palatal plates are expanded and create undercuts. These undercuts may interfere with denture comfort.

This is simply done with finger pressure on the labial and palatal or buccal and lingual cortices to compress them together as tolerated by the tissues.

Technique: Simple Alveoloplasty Simple alveoloplasty can be done in conjunction with or after extraction of teeth. It is typically intended to remove sharp edges, bony prominences, or undercuts in preparation for prosthetic rehabilitation. This is a surgical technique that should be as conservative as possible Figure , A and B.

Alveolectomy

Has sharp blades which are squeezed together by the handles to cut the bone. Major designs which are side-cutting forceps and side and end-cutting forceps Can be used to remove large amounts of bone efficiently Bone file Double ended instrument Cannot be used for removal of large amount of bone and only used for final smoothing. Teeth of the bone files are designed in a fashion that bone can be smoothened by pull stroke only Pushing stroke of bone files can cause crushing of bone and this should be avoided. Rotary burs and handpieces Preoperative Planning[ edit ] The clinical examination focuses on bony projections and undercuts, large palatal and mandibular tori, and other gross ridge abnormalities. A dentist should always evaluate the interarch relationship in 3 dimensions while doing treatment planning for denture patients. Radiographs examinations are indicated for any retained root tips, impacted teeth, bony pathology and impacted teeth to minimise post denture insertion discomfort. The degree of maxillary sinus pneumatization, and the position of the inferior alveolar canal and mental foramina are important as well to avoid impingement of denture on these vital structures which may trigger more problems to the patient.
