Abstract
Background: Rehabilitation for segmental mandibular defect is vital for mastication function and facial aesthetics. Interestingly spontaneous bone regeneration after segmental mandibulectomy sporadically occurs to avoid further bony rehabilitation. This study aimed to assess the potential of spontaneous bone regeneration in the treatment of mandibular defects.
Material and methods: An electronic search was conducted using the PubMed, EMBASE, Wiley Online Library, and Cochrane Library databases to identify eligible studies. Critical appraisal of the included articles was done using the Joanna Briggs Institute critical appraisal checklist.
Results: A total of 35 studies, including 60 patients, that investigated spontaneous bone regeneration after segmental mandibulectomy were included. Among these patients, 39 (65%) were male and 21 (35%) were female, with a mean age of 20.81 ± 16.38 years. Periosteum was completely and partially preserved during mandibulectomy in 25 and 13 patients, respectively. Continuous bone regeneration between mandibular stumps was observed in 53 (88.3%) patients during follow-up. Although the mandibular stump was not stabilized in 13 (21.67%) patients, continuous bony regeneration still occurred, with a mean recovery period of 30.29 months. This was significantly greater than the overall average recovery time of 19.87 months.
Conclusions: Spontaneous bone regeneration could occur in segmental mandibular defects, particularly in young patients with intact periosteum and rigid mandibular stump fixation.
