Mandibular anterior ridge extension: a modification of the Kazanjian vestibuloplasty technique.
OBJECTIVE
A modification of the secondary epithelization vestibuloplasty technique described by Kazanjian that eliminates the sharp V in the depth of the extended vestibule and counteracts shallowing of the sulcus is presented.


METHODS
Ten consecutive patients indicated for anterior mandibular secondary epithelization vestibuloplasty were treated. A bipedicled mucosal flap was developed in the labioalveolar mucosa for lining the extended vestibular depth. A comparison was made of the vestibular depth measured from the crest of the ridge to the junction of the attached mucosa both preoperatively and postoperatively.


RESULTS
Healing of raw surfaces was uneventful. The mean preoperative anterior mandibular vestibular depth was 3.5+/-1.1 mm. After 6 months, the mean anterior mandibular vestibular depth was 9.2+/-1.7 mm, a statistically significant difference (P < .05). The mean gain in vestibular depth was 5.7+/-2.2 mm.


CONCLUSIONS
Overcorrection is unnecessary with this modification. Elimination of the sharp V in the extended vestibular depth enables denture fabrication with better flange extension and improved oral hygiene.
