| Abstract | ||
| Aims: To evaluate the effects of orthodontic treatment, sex on the maxillary arch measurements, anatomical landmarks position, dimensional differences of artificial teeth selection and position on the comfort for treated partially edentulous patient; with and without previous orthodontic treatment. Materials and Methods: two groups of patients: (Males and females) included in this study. First group were with Orthodontic group classified as: Angle class I malocclusion, crowding more than 5 mm, there were 48 in number. Second group were 32 in number, and they're partially edentulous (with previous orthodontic treatment or without as a control group), they were selected with special criteria. A 192 dental stone casts were prepared, and 64 linear measurements were done for each individual cast of the first group, and 22 measurements for the second group. Crom–Cobalt (Cr–Co.) partial dentures were constructed for the second group individuals, follow up for 3–6 months to detect the comfort of the patient in relation to mean differences in the length measurements of the saddle area were recorded. Results: Incisal canine dimension showed a marked expansion of right side (0.7342 mm) post orthodontic treatment, constriction in the upper inter 1st molar distance 2.7334 mm in relation to control. Anatomical landmark (canine to hamular notch right and left post orthodontic treatment), in female showed an increase in measurements in relation to male. Length difference of free end saddle area of partially edentulous control group in relation to partially edentulous patient with orthodontic treatment was about 2.987 mm. An increase in percentage of comfort of control patients wearing removable prosthesis was shown in female. Conclusions: Mean values of the all measurements were generally higher in the males than females post orthodontic treatment. Increase in the arc measurements, but with constructions in the inter–molar distance, anatomical landmark labial surface of the central incisors to the incisive papilla, and canine to hamular notch for both groups. Length of artificial teeth of free end partially edentulous with orthodontic treatment was reduced, but the comfort after prosthodontic treatment was higher in female of both groups | ||
