Flapless implantology Treatment planning for the edentulous posterior maxilla

Implant placement using a flapless procedure in the posterior maxilla with insufficient bone height is one of the most promising procedures in flapless implant surgery. A treatment approach to the posterior maxilla is based on the available bone height between the floor of the antrum and the crest of the residual ridge in the region of the ideal implant locations.

Several treatment options are available for an edentulous posterior maxilla. When sufficient bone height (>12 mm) is available, flapless implant surgery using a mini-incision technique is preferred. Socket lift and simultaneous flapless implant placement are selected when 10-12 mm of vertical bone is present. To obtain the 12 mm of vertical bone necessary for improved implant survival, the antral floor is elevated through the implant osteotomy, up to 2mm.

Flapless implant surgery reduces the bone loss of the crest during the initial healing period, thus contributing to enhanced implant stability.

A particle bone sinus graft with immediate or delayed flapless implant placement is indicated when 5 – 10 mm of vertical bone are present.

The authors advocate Bio – Oss grafting. Bio-Oss particle grafting is performed using a small bone window 5 mm in diameter.

The window is created using a vertical incision approximately 8  mm in length, and it is made on the buccal cortical plate about 8mm away from the alveolar crest.
