Complications in implant surgery by Summer's technique: benign paroxysmal positional vertigo (BPPV).

The aim of this study is to show the correlation between implant surgery using an osteotomic technique and benign paroxysmal positional vertigo (BPPV). The case of a 55-year-old patient submitted to oral implant surgery in the 2.3 area is described. The ridge was thin in this particular location and therefore the maxillary expansion technique according to Summer was preferred. After removing the sutures, the patient suffered from vertigo and was in a confusional state. The patient was therefore placed in the Tredelenburg's position and a few minutes later he felt better. However, the symptomatology that seemed disappeared was present again the following day. A careful check-up showed the presence of BPPV, treated as described in this paper.
