AB - The purpose of this study was to determine how the growth rates of certain cranial base and midfacial points and dimensions were affected by force application to the mandible by the chin cup. Control and treated samples consisting of Japanese girls with skeletal Class III relationships were analyzed. Each sample consisted of lateral cephalometric radiographs taken annually (control group) or semiannually (treated group) from early childhood through adolescence. The control sample was composed of seven persons and the treated sample of ten persons. The subjects of the treated sample were required to wear a chin cup a minimum of 12 hours per day. The total force delivered was 500 g, 250 g per side, and the direction of force was, on average, through the condyle. No other appliances were used. The results of this study indicate that the chin cup causes a closing of the cranial flexure angle N-S-Ba, inhibits posterior growth of the point basion, and imposes a vertical growth tendency on the points nasion and sella. The chin cup significantly inhibits anterior and posterior vertical maxillary growth and growth of upper anterior facial height. Because development of vertical posterior facial height is inhibited more than anterior facial height, a clockwise rotation of the maxilla occurs. The chin cup also causes flaring and a decrease in eruption rate of the maxillary incisors. It has no effect on the eruption rate of the maxillary molars, but accelerates their rate of mesial movement as compared with controls.(ABSTRACT TRUNCATED AT 250 WORDS) MH - Adolescence ; Cephalometry ; Child ; Child, Preschool ; *Extraoral Traction Appliances ; Facial Bones/*GROWTH & DEVELOPMENT ; Female ; Human ; Malocclusion, Angle Class III/ THERAPY ; Maxilla/GROWTH & DEVELOPMENT ; *Orthodontic Appliances, Removable ; Prognathism/THERAPY ; Skull/*GROWTH & DEVELOPMENT ; Vertical Dimension SO - Am J Orthod Dentofacial Orthop 1986 Dec;90(6):475-83 2 UI - 87045966 AU - Bachmayer DI ; Ross RB ; Munro IR TI - Maxillary growth following LeFort III advancement surgery in Crouzon, Apert, and Pfeiffer syndromes. AB - This was a cephalometric study of maxillary growth following LeFort III osteotomy in children with Crouzon, Apert, and Pfeiffer (CAP) syndromes. Nineteen children who had undergone LeFort III advancement osteotomies were followed postoperatively for an average of 5.3 years. Data for horizontal and vertical maxillary growth increments were obtained and compared with data of a control group of unoperated CAP children and with normal data. The findings indicate that horizontal maxillary growth following surgical treatment is negligible (less than 0.1 mm/yr), and differs from unoperated CAP children (0.7 mm/yr) and normal children (1.3 mm/yr). Vertical maxillary growth following surgery is identical to that in unoperated CAP and normal children, amounting to 1.3 mm/yr. The LeFort III osteotomy during childhood is a justifiable procedure for physiologic and psychologic reasons. Horizontal maxillary growth, for all practical purposes, is eliminated by this procedure and a subsequent maxillary advancement is invariably required at the completion of growth.

By using this technique, a more predictable result may be attained with respect to jaw relations, obturator height, and lip position, all of which may be compromised in the edentulous patient with a postsurgical maxillary defect.

AB - Two groups of patients were selected from the State University Dental School in Ghent--an experimental group with tooth agenesis and a control group with complete dentitions. Skeletal anomalies were diagnosed by means of lateral cephalograms according to the Sassouni analysis. The amount of crowding was measured on standardized photographs by Little's Irregularity Index. The prevalence of Class I skeletal relationship appeared to be significantly higher in the agenesis group than in the control group. Skeletal deep- and normal-bite cases occurred more often in patients with hypodontia than in the control group. As far as crowding was concerned, it was less pronounced in the hypodontia group (lateral segments) than in the control group. This conclusion held true only when the "amount: of crowding was not taken into account.

AB - A preprosthetic procedure for treatment of severe atrophy of the maxilla is reported. By means of the horse-shoe sandwich osteotomy of the edentulous maxilla with interposition of iliac crest or ribs in combination with a modified submucous vestibuloplasty there is the possibility of increasing the vestibular and palatal height and improving the mucosal contour in one surgical session. The method, which is described in details, avoids the disadvantages of the earlier operation methods of direct osseous augmentation and the Le Fort-I-osteotomy of the edentulous maxilla. The satisfactory results of 15 operated cases in the observation period of 3 to 15 months are reported. There is only little bone resorption. The horse-shoe sandwich osteotomy might therefore be the method of choice in cases of extreme atrophy of the maxilla.

AB - The purpose of this prospective study was to re-examine the relative importance of various factors in the pathogenesis of angular cheilitis. Sixty-four patients with cheilitis were examined clinically and microbiologically. In addition, a subsample of 23 patients was examined for serum iron and transferrin. The clinical appearance of the lip lesions fell into 4 categories. A ground rhagad at the corner of the mouth involving adjacent skin, was the most frequent type among dentate patients, whereas among denture wearers a deep lesion following the labial marginal sulcus was frequently observed. Dentate patients and denture wearers with cheilitis often had atopic constitution or cutaneous diseases. Pathogenic microorganisms were cultured from the lesions in all 64 patients; Staphylococcus aureus in 40 patients and Candida albicans in 45. The results of this study indicate a correlation between angular cheilitis and pathogenic microorganisms. Furthermore, among dentate patients, a correlation exists between cutaneous discomfort and angular cheilitis. Other etiological factors suggested for this disorder were found to be of subordinate importance.

AB - This study examines the short-term stability of the mandible following mandibular advancement surgery in which skeletal suspension wires were used in addition to dental maxillomandibular fixation. Twenty adults underwent sagittal ramus osteotomies. No concomitant surgical procedures were performed. Maxillomandibular fixation consisted of wiring between the upper and lower orthodontic brackets and circummandibular wires connected to the piriform aperture or anterior nasal spine wires for eight weeks. Cephalograms were analyzed during this period to evaluate skeletal stability. A statistically insignificant mean horizontal relapse of 8.9% was found at pogonion during the period of fixation. Significant vertical intrusion of the anterior mandible occurred, however, with a mean superior movement of pogonion of 0.83 mm (P less than or equal to 0.05). Dental changes noted were uprighting of the maxillary incisors and flaring of the mandibular incisors. In comparison with the results of other studies in which dental maxillomandibular fixation was used alone, the results of this study indicate that the use of skeletal suspension wires is advantageous in the prevention of horizontal skeletal relapse.

AB - This article describes the Active Vertical Corrector (AVC), which is a simple removable or fixed orthodontic appliance that intrudes the posterior teeth in both the maxilla and mandible by reciprocal forces. By the use of effective posterior intrusion of teeth, the mandible is allowed to rotate in upward and forward directions. The uniqueness of this appliance is that it allows the clinician to correct anterior open bite problems by actually reducing anterior facial height. This treatment approaches the problem at its cause (overeruption of posterior teeth) and provides better facial balance and esthetics than most conventional orthodontic treatment procedures. Problems formerly thought to require orthognathic surgery can now be treated successfully with the AVC.

AB - Cephalometric and clinical examination data from a group of 62 subjects with documented structural and functional changes in the temporomandibular joint were compared with that of a group of 102 subjects from a normative sample. The purpose of the study was twofold: to provide a description of a sample of subjects with documented TMJ alterations and to make cephalometric comparisons between this sample and a sample of control subjects from the general population. Results indicated an increased proportion of subjects with "high plane: characteristics and a decreased proportion of subjects with "low plane: characteristics in the experimental sample, but little or no differences in dental and occlusal parameters were found. There were no differences in the proportions or characteristics of subjects in any Angle classification group. There was a tendency, based solely on descriptive statistics, for the group of experimental subjects with negative trauma histories to exhibit an increased proportion of "division 2: incisal relationships.

AB - To analyze the profile properly, the size and position of the bases of the facial thirds must be known. In this study an average face was created by standard cephalometrics. The bases of the facial thirds were then moved in the horizontal or vertical direction, and the soft tissue profile was drawn to correspond to the skeletal changes. The results show how underlying skeletal abnormalities influence the profile. The terms used to describe the size and position of the bases serve as an aid in profile planning.

AB - To evaluate the clinical crown length relative to fixed-appliance orthodontic treatment of excessive overjet and deep overbite and to correlate such changes to the vertical dental height, the following measurements were undertaken for 12 females and 8 males, between the ages of 16 and 20 years, on three separate occasions--2 days before banding, 2 days after debanding, and 12 months after debanding: (1) overjet, overbite and dental height measured from right lateral cephalometric x-ray films; (2) clinical crown length, measured from study models, of 400 teeth divided into four groups--maxillary incisors and canines (120 teeth), maxillary second premolars and first molars (80 teeth), mandibular incisors and canines (120 teeth) and mandibular second premolars and first molars (80 teeth); and (3) gingival condition by means of the gingival index of L:oe and Silness. Fixed edgewise orthodontic appliances were used and the four first premolars were extracted. From the results of the investigation, the following conclusions were evident: after a 12-month follow-up observation period, the achieved reduction in overjet, overbite, and dental height showed relapses of 9%, 11%, and 29%, successively; only 7% of the 400 teeth examined showed reductions in clinical crown length. This change was probably the result of gingival hyperplasia. The gingival condition greatly improved by approximately 64% after 12 months of debanding, accompanied by 25% to 50% relapse in the amount of change in clinical crown length (noted 2 days after debanding); and the intrusive tooth movement during orthodontic correction of deep overbite was the result of vertical movement of the tooth, with its investing tissues and soft-tissue attachment, into the jaws.(ABSTRACT TRUNCATED AT 250 WORDS) MH - Adolescence ; Adult ; Cephalometry ; Female ; Gingiva/ANATOMY & HISTOLOGY ; Human ; Male ; Malocclusion/*THERAPY ; Odontometry ; Time Factors ; Tooth/*ANATOMY & HISTOLOGY ; *Tooth Movement, Minor ; Vertical Dimension SO - Am J Orthod 1986 Mar;89(3):246-50 15 UI - 86104043 AU - Banks PA TI - An analysis of complete and incomplete overbite in class II division 1 malocclusions (an analysis of overbite incompleteness). AB - A retrospective cephalometric study of Class II Division 1 malocclusions was carried out. Sixty patients with complete overbites were compared with another group of 60 matched in every respect, with the exception of having incomplete overbites. All patients were in the permanent dentition stage and aged between 10 and 14 years. An incomplete overbite was related to vertical variation in the skeletal pattern. This was demonstrated by greater anterior lower facial height, greater gonial angle, and steeper mandibular plane inclination. Incisor alveolar heights and molar heights did not vary between the groups. No differences between groups were noted for the degree of overjet reduction achieved during treatment, or in post retention relapse of overbite and overjet.
