Facial asymmetry is prominent with individuals with unilateral bone resorption and can lead to decreased quality of life.. The purpose of this study was to investigate the influence of maxillary obturator prostheses on facial morphology of individuals with unilateral maxillary defects by using 3-dimensional digital stereophotogrammetry.. The facial data of 8 participants with unilateral maxillary defects were acquired with a noncontact 3-dimensional digitizer, both with and without maxillary prostheses. The mid-facial plane was established by overlapping an original facial image with its mirror image. Displacement at 18 measurement points, including 7 bilateral pairs, was compared between the 2 sides, with and without the prostheses. Asymmetry indices of these 7 pairs also were calculated. Multivariate repeated-measures ANOVA was used to determine differences.. Displacements of the lateral and inferior points at the ala of the nose were significantly greater on the defect side than on the normal side. The distances between the ideal and defect side points at the superior ala, the upper lip, and the angle of the mouth decreased significantly with the prosthesis. No significant differences were found in asymmetry indices, but the angle of the upper lip line to the mid-sagittal plane increased significantly with the prosthesis.. The 3-dimensional analyzing method developed in this study can be useful in evaluating facial reconstruction with maxillary obturator prostheses with individuals with unilateral maxillary defects. The prostheses affect the region of the nasal ala, the upper lip, and the angles of the mouth.

This article reports a longitudinal follow-up of a 15-month-old child with dental trauma resulting from an attack by a dog. The injury consisted of laceration of the facial tissues and loss of the upper central deciduous incisors, in addition to loss of bone tissue in the same area. A malformation of the crown of the right central permanent incisor and complete change of the shape of the left central permanent incisor were observed. The etiological factors of childhood injuries as well as the importance of dental emergency care are discussed and the 14-year clinical and radiographic follow up of the case is presented.

Soft and hard tissue defects of the cranio- and maxillofacial area, especially after an avulsion injury, are challenging to reconstruct. Sophisticated soft and hard tissue transfer techniques have allowed satisfactory reconstruction of the gross anatomic structure. However, these methods do not allow optimal restoration of fine anatomic detail or function. The advent of dental implants and modified dental implants for craniofacial applications has allowed maximization of cosmetic and functional restoration. Prosthodontists are capable of fabricating subunits of the cranio- and maxillofacial area with fine detail, reproducing the coloring, texture, and idiosyncrasies of a patient's native skin. Dental implant technology has allowed these prostheses to be bone anchored, yielding a reproducible and stable attachment. This method of attachment in turn allows flexibility in the design of the prosthesis, to maximize restoration, and imparts an increased sense of confidence to the patient. Illustrated are six examples demonstrating the versatility of dental implants in the reconstruction of avulsion injuries of the cranio- and maxillofacial complex.
