This report describes a method to expand cleft segments of patients with cleft lip and palate prior to the secondary alveolar bone graft (ABG) using a reprogrammable nickel titanium expander. The expander can be reprogrammed with electric current to the desired width for each patient and delivers a gradual slow expansive spring force that expands and aligns the segments without further adjustments. Reprogramming the expander eliminates the need for multiple appliances and reduces chair time and patient appointments...

The purpose of this study was to evaluate the preservation of alveolar dimensions in human fresh extraction sockets filled with a composite bovine bone graft by means of design of single-blind randomized clinical trial. Forty participants had monoradicular teeth extracted (one teeth in each participant), and after were randomly divided into 2 groups: individuals whose fresh sockets were filled with the composite heterologous bone graft (Biomaterial Group), or with blood clot (Control Group). After extraction, the fresh sockets were measured at their greatest mesiodistal (MD) and bucco-lingual/palatal (BL/P) distance...

BACKGROUND: Autogenous intraoral block grafting is the gold standard augmentation technique for moderate-to-severe horizontal ridge deficiency. However, the graft undergoes variable resorption during healing that might jeopardize the outcome of the procedure. Several studies hypothesized that covering the graft with a membrane decreases the amount of graft resorption, but this effect is not established in the literature. OBJECTIVE: The objective of this study is to assess the clinical value of covering intraoral block grafts with membranes in horizontal ridge augmentation regarding graft resorption (primary outcome), graft success, net bone gain, and complications (secondary outcomes)...

Interdental distraction osteogenesis has been introduced as a successful treatment protocol for repairing large clefts. In this article, a new method for reconstruction of the premaxilla in 2 bilateral cleft lip and palate patients is introduced. The aim was to distract the lateral segments through the curve of the dental arch, achieve complete closure of the gaps, and use the premaxilla as a bone graft. Patient 1 (20-year-old female) had double jaw surgery before but presented residual alveolar cleft and small premaxilla...

Alveolar transport distraction osteogenesis (ATDO) is an alternative treatment method to vertical alveolar distraction osteogenesis in cases of large bony defects, especially when the bone is limited in size. ATDO was performed in 10 patients with 12 defects. The mean age of the patients was 39.1years. The average bone length gain was 18.2mm. Implants were inserted following a 3-month consolidation period. Three patients needed additional bone grafting for horizontal widening. Final prosthetic rehabilitation was performed at least 3 months following implant insertion...

Objectives: To compare parameters related to impacted canines at the cleft versus the normal contralateral side and with non-impacted canines at the cleft side in unilateral cleft lip and palate (UCLP) patients. We also aim to search for possible associated parameters enabling prediction of canine impaction in these patients. Materials and methods: Ninety-five non-syndromic UCLP patients were included and divided into group A (n = 41 patients) with unilateral impacted canines at the cleft side (A1) and spontaneously erupted canines at the non-cleft side (A2) and group B with spontaneously erupted canines at the cleft side (n = 54 patients)...

BACKGROUND: Periodontal disease is a condition affecting tooth-supporting tissues (gingiva, alveolar bone, periodontal ligament, and cementum), with the potential of introducing severe adverse effects on oral health. It has a complex pathogenesis which involves the combination of specific micro-organisms and a predisposing host response. Infrabony defects are one of the morphological types of alveolar bone defects that can be observed during periodontitis. Recent approaches for the treatment of infrabony defects, combine advanced surgical techniques with platelet-derived growth factors...

Hydroxyapatite (HA) is the main mineral component of bone and teeth. HA is often used as a bone substitute and especially in its granular form it is osteoconductive and osseointegrating as shown by many investigations in animals and humans. HA granules are used for filling bone defects, but they have poor handling qualities and retention at the surgical site, leading to graft voids between the granules and bone tissue and resulting in mechanical instability. Furthermore HA implantation is not constantly followed by favorable results, especially when it is carried out for augmentation of the alveolar ridge...

BACKGROUND: Resection of maxillofacial may cause a series of complications such as loss of facial deformity, dysfunction, and psychological distress. Mandibular reconstruction following resection still remains difficult. METHODS: A 18-year-old male patient with mandibular ameloblastoma was admitted in the hospital of stomatology. The tumor was dissected and the defect was reconstructed using vascularized fibula graft. One year later, distraction osteogenesis (DO) was performed on the fibula graft to augment the alveolar bone for dental implants...
