ABSTRACT
INTRODUCTION:
Upper alveolar nerves, when injured during Le Fort I osteotomies, alter maxillary tooth sensitivity. We had for aim to analyze post-operative maxillary tooth sensitivity recovery. MATERIAL ANDMETHODS:
We conducted a prospective study in a series of patients having undergone Le Fort I osteotomy, with, or without mandibular osteotomy or intermaxillary disjunction (IMD). The direction and range of displacement of the maxillary bone were recorded. One tooth in each alveolar sector (incisivocanine, premolar, molar) was tested with an electric stimulator for each patient. The tests were performed before (D-1), and after surgery (D2 or day+2, D+15, M2 (or month +2), M3, and M6).RESULTS:
Twenty-two patients were included. Among the tested teeth, 91.9 % were sensitive at D-1. At D2, only 12.7 % of teeth were sensitive. At D15, M2, M3, and M6, the sensitivity was respectively 33.3 %, 43.1 %, 50 %, and 61.8 %. The recovery of sensitivity was faster in young patients (under 35 years of age) and for upper middle and superior alveolar nerves. There was no difference regarding the direction of maxillary movement.DISCUSSION:
Among the teeth that were sensitive before surgery, 87.3 % had not regained sensitivity at D2. The recovery of sensitivity increased at D15. A great displacement of the maxillary bone was an aggravating factor for loss of tooth sensitivity.Palavras-chave
