Alveolar ridge preservation is of great importance for successful implant therapy. This study investigated the effects of a xenogeneic tridimensional collagen matrix (CM) in conjunction with deproteinized bovine bone mineral blended with 10% collagen (DBBM-C) on the healing of 12 intact extraction sockets in the esthetic area. Cone beam computed tomograpy examinations revealed nearly stable alveolar ridge dimensions (> 90% of the ridge horizontal dimension was preserved). New bone formation of approximately 45% and adequate resorption of the grafted material were histologically observed...

BACKGROUND Short dental implants are considered an alternative method of treatment to the maxillary sinus elevation and bone augmentation procedure at the sites of a reduced alveolar ridge height. The aim of the study was to determine the most effective therapeutic approach for a single tooth replacement in a reduced maxillary alveolar crest. MATERIAL AND METHODS We enrolled 30 partially edentulous patients having a residual crestal height of 6 mm and a minimal width of the alveolar ridge of 6-7 mm: 15 patients received regular dental implants (OsseoSpeed™ L11 Ø4 mm and L13 Ø4 mm) and the implantation was preceded by the sinus lift procedure from a lateral window approach with the application of a xenogeneic bone graft, whereas the remaining 15 patients received short implants (OsseoSpeed™ L6 mm Ø4 mm) without the sinus lift and augmentation procedure...

Growth deficiency of the maxilla is a frequent finding in patients with complete unilateral cleft lip and palate. When the sagittal discrepancy is severe, orthodontic treatment combined with orthognathic surgery is required. This article reports the treatment of a girl born with unilateral cleft lip and palate who had lip and palate repair at 3 and 12 months of age, respectively. At 3 years of age, she already showed a severe anteroposterior maxillary deficiency with an anterior crossbite in the deciduous dentition...

BACKGROUND: Great interest has recently been focused on tooth and tooth derivatives as suitable substrates for the treatment of alveolar bone defects. Here, we propose the use of demineralized baby teeth (BT) as potential grafting materials for bone augmentation procedures. METHODS: Particles of human BT (Ø < 1 mm) were demineralized by means of a chemical/thermal treatment. Demineralized BT particles were thoroughly characterized by scanning electron microscopy/energy dispersive X-ray analyses to evaluate the effects of the demineralization on BT topography and mineral phase composition, and by enzyme-linked immunosorbent assays (ELISA) to quantify collagen and bone morphogenetic protein-2 (BMP-2) protein contents...

The aim of this cohort study was to investigate the relationship between crestal bone levels and crown-to-implant ratio of ultra-short implants, after functional loading. 60 patients with single or partial edentulism and alveolar bone atrophy were enrolled and treated between December 2009 and January 2016. Without using bone-grafting procedures, patients were rehabilitated with ultra-short implants characterized by a micro-rough surface and a 6-mm length. Clinical and anatomical crown-to-implant (C/I) ratios and crestal bone levels (CBL) were measured after a follow-up period ranging from 12 to 72 months; all peri-implant and prosthetic parameters were recorded...

BACKGROUND: Particulate anorganic bovine bone matrix (ABBM) is extensively used for alveolar ridge preservation (ARP). This study is to evaluate the potential of ABBM/gelatin cryogel scaffold of regular (250-1000 μm) and small (50-100 μm) particles for ARP. METHODS: ABBM was either condensed in a gypsum ring to simulate filling of ABBM in a defect or incorporated into a gelatin cryogel scaffold to disperse ABBM. Condensed regular-sized or small-sized ABBM (rABBM or sABBM) (±BMP-2) were subcutaneously implanted in rats to evaluate biocompatibility and osteogenic potential...

INTRODUCTION: One of the most common esthetic complaints among dental patients is a gingival smile, which may be of multifactorial etiology, e.g. gingival hyperplasia, skeletal deformities featuring overgrowth of the anterior maxilla, altered passive eruption, maxillary alveolar tooth extrusion, fine lip and hypermobility of lip elevator muscles, which must be diagnosed prior to treatment so that the appropriate management approach can be selected. Maxillary overgrowth may give rise to subnasal skeletal depression where the upper lip retracts to during smiling, causing gingival exposure...

OBJECTIVE: It is necessary to preserve height and thickness of the alveolar bone to facilitate rehabilitation with osteointegratable implants or simply to maintain bone integrity after extraction. Biomaterials associated with resorbable or non-resorbable membranes, when placed in the region of the socket, may contribute to avoid this unwanted reabsorption. OBJECTIVE: The objective of this study was to evaluate the distance of the crest of alveolar ridge to the cementoenamel junction (CEJ) of the lower second molars and the bone density of the third molar socket filled with Gen-Tech®, 5 years after an exodontia using cone beam computed tomography (CBCT) to visualize the central region of the sockets, without overlapping of the buccal and lingual cortical bones...

Reconstruction can be very problematic in the case of mandibular alveolar bone loss, which can also hinder the implant restorative treatment. The aim of the study was to present current views on reconstructing the alveolar part of mandibular bone, which allows the insertion of implants and then the placement of denture. Based on the available literature, the efficacy of various techniques of filling of mandibular bone losses was described and compared. Reconstruction with autogenous bone block graft had been used as a gold standard...
