Postoperative Assessment of Secondary Alveolar Bone Grafting Using a Combination of β-Tricalcium Phosphate and Chin Bone for Patients With Unilateral Cleft Alveolus.

Secondary alveolar bone grafting (sABG) is crucial for the treatment of alveolar clefts. However, postoperative bone formation using a graft material comprising a mixture of beta-tricalcium phosphate (β-TCP) and chin bone has been previously evaluated only 2-dimensionally, using plain radiographic images. In this study, the authors aimed to retrospectively and 3-dimensionally assess bone formation following sABG in patients with an alveolar cleft, using a mixture of β-TCP and chin bone.

Clinical outcomes of gingivoperiosteoplasty for unilateral cleft lip and palate performed in early childhood.

Conventional gingivoperiosteoplasty (GPP) performed during infancy adversely affects maxillary development. However, the outcomes of this procedure in early childhood have rarely been reported. Therefore, we examined the postoperative outcomes of GPP conducted in patients aged 1.

Swallowing-like activity elicited in neonatal rat medullary slice preparation.

Swallowing is induced by a central pattern generator in the nucleus tractus solitarius (NTS). We aimed to create a medullary slice preparation to elucidate the neural architecture of the central pattern generator of swallowing (Sw-CPG) and record its neural activities. Experiments were conducted on 2-day-old Sprague-Dawley rats (n = 46).

Maxillary Development and Dental Arch Relationships Following Early Two-Stage Palatoplasty: A Comparative Study.

Objective: To examine skeletal morphology and dental arch relationships at 8 years of age following early 2-stage palatoplasty, which consists of soft palate plasty at 1 year of age and hard palate closure at 1.5 years of age, and to compare the results with those of conventional pushback palatoplasty.

Design: Retrospective.
