Teeth replacement with dental implants is a concern in maxillary posterior region due to pneumatization of the maxillary sinus. Indirect maxillary sinus floor augmentation is one of the techniques to overcome this problem. Studies on animal models showed that topical application of melatonin hormone at the implant site preparation may enhance osseointegration of dental implants. Here we report a case of melatonin application after closed elevation of the left maxillary sinus lining and progressive loading of one-piece dental implant at a missing maxillary premolar. This implant was subjected to progressive immediate loading after 2 weeks of initial placement in a 23 years old female patient. Melatonin gel was injected into the osteotomy site after indirect maxillary sinus lift. The patient was recalled for follow up at 1, 3, 6 and 12 months post-loading. The implant was considered successful after 12 months of follow up. An increase in the residual ridge height was 0.9 mm. Changes in the marginal bone level and implant stability were within the acceptable limits for a successful implant. This is the first case study of an indirect sinus lift technique made with melatonin gel, as a graft material, in combination with progressive immediate loading of one-piece dental implant. After one year of follow up, predictable outcomes are evident in a patient with resorption of the posterior left maxilla due to sinus pneumatization.
