Purpose. Bone atrophy after tooth loss may leave insufficient bone for implant placement. We compared volumetric changes after autogenous ramus block bone grafting (RBG) or guided bone regeneration (GBR) in horizontally deficient maxilla before implant placement. Materials and Methods. In this retrospective study, volumetric changes at RBG or GBR graft sites were evaluated using cone-beam computed tomography. The primary outcome variable was the volumetric resorption rate. Secondary outcomes were bone gain, graft success, and implant insertion torque...

AIM AND OBJECTIVES: Edentulism is an incapacitating and irretrievable condition which can lead unswervingly to functional limitation, physical, psychological and social handicap. Maintenance of bone after tooth loss to improve retention, function, and performance of the restoration is a challenging task. The existence of a thin edentulous ridge signifies a clinical situation that is more complex for the placement of endosseous implants. Dental rehabilitation of the edentulous ridges with oral implants has become a routine treatment modality in the last few decades with consistent long term results...

BACKGROUND: Severe obstructive sleep apnoea (OSA) is a life threatening condition associated with Pierre Robin sequence (PRS) due to mandibular micrognathia and glossoptosis. Often these patients require tracheostomy at an early age which has high morbidity. Distraction osteogenesis (DO) is an accepted method of treatment for patients with hypoplastic mandible to achieve mandibular lengthening without need for a bone graft. It has also been used in respiratory distressed neonates and infants to avoid tracheostomy...

This is a case report of a custom titanium ridge augmentation matrix (CTRAM). Using cone beam computed tomography (CBCT), a custom titanium space-maintaining device was developed. Alveolar ridges were virtually augmented, a matrix was virtually designed, and the CTRAM was additively manufactured with titanium (Ti6Al4V). Two cases are presented that resulted in sufficient increased horizontal bone volume with successful dental implant placement. The CTRAM design allows for preoperative planning for increasing alveolar ridge dimensions to support dental implants, reduces surgical time, and prevents the need for a second surgical site to gain sufficient alveolar ridge bone volume for dental implant therapy...

BACKGROUND: It has been previously hypothesized that oral microbes may be an etiological link between rheumatoid arthritis (RA) and periodontal disease. However, the mechanistic basis of this association is incompletely understood. Here, we investigated the role of periodontal bacteria in induction of joint inflammation in collagen-induced arthritis (CIA) in B10.RIII mice. METHODS: CIA-prone B10.RIII mice were infected orally with a polybacterial mixture of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia for 24 weeks before induction of CIA...

Autogenous bone-block grafts are the "gold standard" for block bone grafting, but have several disadvantages. Allografts have the potential to overcome these disadvantages. The purpose of this study was to evaluate the clinical and histomorphometric features of demineralized freeze-dried cortical block allografts (DCBA) used for ridge augmentation. Eleven patients who showed bone deficiencies of <5 mm in the horizontal plane were included in this study. The recipient sites were reconstructed with DCBA...

To ensure a successful dental implant therapy, the presence of adequate vertical and horizontal alveolar bone is fundamental. However, an insufficient amount of alveolar ridge in both dimensions is often encountered in dental practice due to the consequences of oral diseases and tooth loss. Although postextraction socket preservation has been adopted to lessen the need for such invasive approaches, it utilizes bone grafting materials, which have limitations that could negatively affect the quality of bone formation...
