Peri-Implantitis is defined as an inflammatory reaction with the loss of the supporting bone in the tissues which surround a functioning implant. The peri-implantitis lesions are often asymptomatic and they are usually detected during the routine recall appointments. Careful probing around the teeth and the implants should be done routinely along with the radiologic evaluation during these check-up appointments. Retrograde peri-implantitis may sometimes prove even more difficult to identify, resulting in the loss of the implant. This paper presents a report of the extensive and the meticulous management of retrograde peri-implantitis and the implant being finally restored to health and the full functional status.

The success rate of the mini implants of 90.9%, is encouraging and hence studies involving larger number patients can be undertaken to study the efficacy of this novel treatment plan.

Dental implants placement can sometimes be limited due to physical conditions, wherein the horizontal space is limited by adjacent teeth and roots or situations in which there is narrow alveolar ridge, By using a narrow diameter implant (NDI), the need for bone augmentation can be avoided. In situations where there is limited horizontal space, a NDI may be the only option to replace a missing tooth.

Placement of endosseous implants into infected bone is often deferred or avoided due to fear of failure. However, with the development of guided bone regeneration [GBR], some implantologists have reported successful implant placement in infected sockets, even those with fenestration defects. We had the opportunity to compare the osseointegration of an immediate implant placed in an infected site associated with a large buccal fenestration created by the removal of a root stump with that of a delayed implant placed 5 years after extraction. Both implants were placed in the same patient, in the same dental quadrant by the same implantologist. GBR was used with the fenestration defect being filled with demineralized bone graft* and covered with collagen membrane**. Both implants were osseointegrated and functional when followed up after 12 months.

Implant related prosthesis has become an integral part of rehabilitation of edentulous areas. Single stage implant placement has become popular because of its ease of use and fairly predictable results. In this paper, we present a series of cases of single stage implants being used to rehabilitate different clinical situations. All the implants placed have been successfully restored and followed up for up to one year.
