[Width relationship between upper and lower anterior teeth].

This study deals with the relationship which exists between upper and lower anterior teeth. Measurements for the width of the upper central incisor, six upper anterior teeth and the six lower anterior teeth were drawn from 98 couple of casts taken from 50 female and 48 male age range 22-27 years old. Our results showed: A) A significant statistical difference exists between male and female regarding the width of upper and lower anterior teeth. B) There is no a statistical significant difference between these two groups regarding the width of the upper central incisor. C) There exists a relationship of 1.3 between upper and lower teeth. D) A relationship of 6.1 between upper anterior teeth to central upper incisor. E) A relationship of 4.7 between lower anterior teeth to upper central incisor.

[Osseointegration and tissue-integrated prostheses].

After surgical uncovering of the fixtures and abutment connection a preliminary impression of the entire ridge and surgical area is made. From the resultant cast an impression tray is fabricated for the final impression. At least 1 week should elapse after abutment connection before final impression is made. The presence of sutures and easily traumatized attached gingival tissues may complicate oral procedures. After the impressions have been made, jaw relationship has been recorded, casts have been mounted on an articulator, and tooth arrangements has been verified, a rigid metal framework is cast in gold or in silver-palladium alloy from a wax-acrylic pattern. The metal construction consists of at least 6 mm of vertical height and buccal-lingual width and sufficient rigidity of the cantileverded sections billaterally. The artificial dentition is then reassembled on the new frame in the predetermined position and examined in the mouth for confirmation of fit and appearance. The prostheses is then temporarily secured to the abutments using small gold screws for approximately 1 month as an adjustment period.
