SIMPLIFIED ONE-APPOINTMENT RECONSTRUCTION OF THE SEVERELY ATROPHIED MANDIBLE: A ONE-SURGICAL VISIT TECHNIQUE, RESTORING HEALTH, FUNCTION AND AESTHETICS
Loss of bone in the mandible after tooth removal is not limited to alveolar bone; basal bone may also be resorbed. This continuing loss of bone is associated with anatomical and facial aesthetic complications and the instability of the mandibular complete denture. Endosteal implants are routinely used to stabilize and support the mandibular prosthesis for the completely edentulous patient and are placed into the remaining native bone. If the remaining vertical bone height is 6mm or greater and the prosthesis is totally implant-supported, grafting has been found unnecessary. However, when mandibular vertical bone height is less than 6mm, grafting is considered necessary, Robert Marx AO 2005.

PREVIOUS TREATMENT CONCEPTS: 6mm or greater bone height body of mandible
IMPLANT PLACEMENT for the mandible involved: IV conscious sedation or general anesthesia, three months healing time for dental implants, second-stage surgery before loading with the patient unable to wear a lower prosthesis during much of the healing time.
M.I.S. TREATMENT CONCEPTS: 6mm or greater bone height body of mandible
A ONE-SURGICAL APPOINTMENT technique for the mandible using Minimal Invasive Surgery: IV conscious sedation with implant placement and immediate implant-loading with an interim prosthesis. Approximately two to four weeks following surgery, the definitive prosthesis was started and inserted for case completion.
CURRENT TREATMENT CONCEPTS: Less than 5mm bone height body of mandible
GRAFTING & IMPLANT PLACEMENT for the severely atrophic mandible involves autogenous hip bone, general anesthesia, three to six months healing time before dental implants are placed and loaded with the patient unable to wear a lower prosthesis during most of the healing time.
M.I.S. TREATMENT CONCEPTS: Less than 5mm bone height body of mandible
A ONE-SURGICAL APPOINTMENT technique for the severely atrophic mandible (less <6mm) using Minimal Invasive Surgery: IV conscious sedation, with implant placement, onlay ridge grafting cPRP but without autogenous hip bone and immediate implant loading with an interim prosthesis. Approximately two to three weeks following surgery, the definitive prosthesis is developed and inserted for case completion. SIMPLIFIED ONE-APPOINTMENT RECONSTRUCTION OF THE SEVERELY ATROPHIED MANDIBLE It is hypothesized that the osteocytes are the primary mechanosensory cells of bone and that as the mandible flexes, they may signal mechanical loading to osteoblasts through release of extracellular nucleotides with chemotactic bone formation in the mandible. This can occur in a few months, following surgery with grafting and implant-loading with the patient unaware of changes. SURGICAL TREATMENT GOALS: RECONSTRUCTION OF THE SEVERELY RESORBED MANDIBLE • Single-stage surgical approach for implant placement with grafting and immediate implant-loading with transitional prosthesis. Patient always has prosthesis during healing for function and aesthetics. • Bone regeneration utilizing banked cancellous bone from human cadaver vertebra with Platelet Rich Plasma and Minimal Invasive Surgical technique. • Increase zone of attached keratinized tissue around implants. • Two-week healing with interim prosthesis, then definitive implant prosthesis placed without loading contact of the grafted and regenerating area with definitive prosthesis. • Patient always has prosthesis (teeth) during healing for function & aesthetics.
