Dental implant surgery has become a routine treatment in dentistry and is generally considered a safe surgical procedure with a high success rate. This breakthrough in oral rehabilitation is based on the concept of Osseo integration. Despite its high success rate, however, many complications have been encountered with its use. One of the most serious complications is the sensation alteration after implant placement in the posterior mandible.
The aim of this study was to evaluate the prevalence of neurosensory disturbances of the inferior alveolar nerve, and the relation between these complications and the qualification of the dental surgeons.
This cross-sectional study considered 1571 patients with 2432 dental implants who were
treated in the period 2014-2016 in 67 privet clinics, Damascus, Syria. 36 of dentists were qualified as a maxillofacial surgeon or dental implantologist the rest of them were not.
By means of a prepared form, the patients’ records and files were examined, information was retrieved, and radiographic images were analyzed. The patients were divided into three groups regarding implants’ proximity to the inferior alveolar canal. 1571 patients with 2432 dental implants, the transient alterations in sensation, occurred in 348 patients with distance between the apex of the implants and the upper wall of Inferior Alveolar Canal ranged 0-0.99 mm, were done by 30 not qualified as maxillofacial surgeons or dental implantologist and one qualified dentist (p=0.008 significant difference).
There is a direct relationship between the qualification of surgeons and the altered sensation after the implant surgery due to the lack of experience in respecting the safe distant (≥2mm), which lead to deep insertion of the implant near to inferior alveolar canal.
