Tapered Submerged Implants in an Augmented Posterior Maxilla After Oroantral Fistula Closure.

Dental implantation in the posterior maxilla is challenging due to anatomic proximity to the sinuses, relative bone quality, and pre-existing sinus diseases. An oroantral fistula (OAF) acts as a pathologic pathway of bacteria and can cause sinus infections and complicate dental implant management. Bony augmentation between the sinus floor mucosa and the oral mucosa at the OAF closure site is another critical consideration.

Long-term survival rates of tapered self-tapping bone-level implants after immediate placement: a positional effective rationale.

Background: Immediate implant placement has gained popularity due to its several advantages. However, immediate placement has its challenges, including concerns about primary stability and bone formation around the implant. The aim of the present study is to evaluate the clinical outcomes of tapered, sand-blasted, and acid-etched internal submerged dental implants in various regions of the jaw bones and to provide a positional rationale for immediate implant placement.

Proper Management of Amalgam Powder Embedded in the Alveolus.

The presence of foreign bodies in the mandible is not listed as a risk factor or absolute contraindication for implant rehabilitation. However, possible complications caused by foreign bodies, such as infection and cyst formation, could lead to implant failure. The authors report a case of dental implant placed 4 months after the surgical removal of embedded amalgam in the mandibular alveolus using a trephine bur and bone grafting with mineralized freeze-dried bone allograft.
