Abstract

Background: Information concerning the maximum bite force in human population is important to clinicalorthodontics. Additionally, the influence of bite force on the vertical stability of any treatment result is important. Thenew position of the dentition should be compatible with the dynamics of the muscular and occlusal forces in allplanes. This study was conducted to 1) to measure and compare maximum bite force, body height and weightamong normal occlusion and malocclusion groups (cl I,cl II,cl III) in both gender 2) to evaluate the correlationbetween bite force and craniofacial morphology, body height and weight.Materials and Methods: The sample consists of 100 Iraqi adult subjects aged 18-25 years. It was classified in to fourgroups: cl I normal occlusion, cl I malocclusion, cl II malocclusion, and cl III malocclusion according to(skeletal) thevalue of ANB angle and (dental)the Angle classification. Each group consist of 25 (13 male, 12 female), Maximumbite force was measured by a digital device (GM10, Naganokeiki, Japan) by putting the sensor part of occlusalforce meter on first molar region, body height and weight were measured by using the Length and WeightMeasuring Standard (Tanita, 2008) and craniofacial measurements were achieved by analysis of lateralcephalometric radiographResults: The highest mean value of maximum bite force was found in normal occlusion followed by class IImalocclusion and then class I malocclusion and the lowest value was found in class III malocclusion, class I skeletalrelationship (cl I normal occlusion & cl I malocclusion group) had larger values of body weight when compared withskeletal class II& class III .Regarding the gender, mean values of maximum bite force and body height are higher inmale than female in normal occlusion and malocclusion groups, There is a positive correlation between maximumbite force and body height and weight in normal occlusion and class I malocclusion ,there is a positive correlationbetween maximum bite force and palatal plane, Ramus plane, mandibular plane, posterior facial height, cranialbase, dentoalveolar height, while there is a negative correlation with anterior facial height, Gonial angle, SN-Mp¢ª,PPMP&SN-PP¢ª angles.Conclusion: The normal occlusion group had larger values of bite force than malocclusion group,the maximum biteforce, body height is gender related, larger body build up was usually associated with larger bite force in class Iskeletal relationship, Individuals with characteristics of larger maxilla ,larger mandible, larger cranial base ,shortanterior facial height long posterior facial height, flat mandibular plane had the largest value of bite force.

Abstract

Background:Growth disorders associated with inborn defects, injuries or surgeries can restrict the development of the palatoalveolar complex and initiate the development of jaw and orthodontic anomaliesAim of the study: to assess the skeletal craniofacial morphology of patients with operated unilateral cleft lip and palateMaterials and Methods: lateral cephalometric radiographs were taken for 20 adult of Iraqi operated unilateral cleft lip and palate patients. Twelve angular measurements and seven linear measurements were compared with control group selected on the bases of satisfactory facial esthetic matching with age.Results: A significant differences were observed between cleft patients and non cleft individuals in that, cleft patients have smaller mean value mandibular angular measurements max-mand angle, N-S-GN angle with short body length while the maxilla demonstrates a retrusive position and results in the concave profile appeared by increase N-A-Pog angle at p<0.05, there is a definite decrease in overall mid facial growth especially in sagittal plane, while the lower anterior facial height shows an increase in length with significantly smaller mean value.Conclusion: that cleft patients have a craniofacial morphology characterized by retruded maxillomandibule complex with a concave profile, when superimposed on that of control group, and smaller anterior cranial length together with shorter mandibular body result in relatively normal spatial mandiblular position through normal S-N-B angle.
