Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization associated with palmoplantar keratoderma and severe periodontitis resulting in complete edentulism in late adolescence. The pathognomonic dental features of PLS are pathologic migration, hypermobility, and exfoliation of the teeth without any signs of root resorption. It has been suggested that an effective way to treat PLS patients presenting early in the disease progression is extraction of the erupted primary dentition or hopeless permanent teeth followed by antibiotic coverage with periodontal therapy for the remaining teeth...

Cone-beam computed tomography (CBCT) scans are used in planning implant treatment to help determine volume of available bone and identify anatomical structures. This enhances planning, particularly when inadequate bone is present in the posterior maxilla due to proximity of the inferior aspect of the maxillary sinus to the crestal bone. To place dental implants into this area, sinus augmentation is often needed to provide sufficient bone volume to support implants and allow prosthetic loading with predictable long-term results...

Suraj Chavda, Liran Levin
Alveolar ridge augmentation can be completed with various types of bone augmentation materials (autogenous, allograft, xenograft & alloplast). Currently autogenous bone is labelled as the "gold standard" due to faster healing times and integration between native and foreign bone. No systematic review has currently determined whether there is a difference of implant success between various bone augmentation materials. The purpose of this paper was to systematically review comparative human studies of vertical and horizontal alveolar ridge augmentation comparing different types of bone graft materials (autogenous, allograft, xenograft & alloplast)...

PURPOSE: Because of limitations of the absorbable collagen sponge (ACS), recombinant bone morphogenetic protein (rhBMP-2) requires a scaffolding device for ridge augmentation. MATERIALS AND METHODS: Twenty-one patients were treated with 37 allogeneic block grafts and rhBMP-2/ACS. Cone-beam computed tomography (CBCT) was used to measure the ridge at 2 points preoperatively, postoperatively, and after graft healing. Dental implants were placed after 6 months of healing...

The present article on the history of dental implants spans beyond the past 100 years of the American Association of Oral and Maxillofacial Surgeons. It was not until the materials and methods became less traumatic to the bone that implants could become firmly attached to the surrounding bone. This phenomenon is now used to replace single and multiple teeth and restore the patient to function and well-being. Many of the methods used to increase denture function are still used with modifications to augment the environment for an implant...

Sinus lift augmentation is a procedure required for the placement of a dental implant, whose success can be limited by the quantity or quality of available bone. To this purpose, the first aim of the current study was to evaluate the ability of autologous periosteum-derived micrografts and Poly(lactic-co-glycolic acid) (PLGA) supplemented with hydroxyl apatite (HA) to induce bone augmentation in the sinus lift procedure. Secondly, we compared the micrograft's behavior with respect to biomaterial alone, including Bio-Oss® and PLGA/HA, commercially named Alos...

REVIEW
Faraj Edher, Caroline T Nguyen
STATEMENT OF PROBLEM: Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear...

The posterior maxilla is challenged with postextraction alveolar bone resorption and pneumatization drive of the Schneiderian membrane that reduces the subantral distance. To overcome such anatomic obstacle a sinus augmentation procedure was introduced either via lateral or crestal approach depending on residual ridge height. The current study evaluated oxidized regenerated cellulose (ORC) as a grafting material versus osteon II by measuring bone gain and graft density, 24 weeks postoperatively. Twenty consecutive patients (24 cases) aged from 20 to 65 years were considered eligible after clinical and radiographic evaluation...
