An improved dental prosthesis for replacing a tooth or teeth in an edentulous space in a patient's mouth either adjacent to existing teeth or between a first tooth anterior of and a second tooth posterior of the edentulous space which tooth or teeth are prepared with occlusal mounting grooves and where indicated indentations on the respective buccal and lingual proximals of the same tooth or teeth for receiving said dental prosthesis; has multi-section infrastructure for fabricating the dental prosthesis which includes, a main support bar or beam having a sized and shaped center section and at least one connecting end for fastening the main support bar on the tooth or teeth adjacent the edentulous space, the connecting end or ends has a predetermined shape, material and is sized to permit adjustment thereof as a function of the mesial-distal length of the edentulous space and the relative position of the tooth or teeth adjacent the edentulous space, secondary support means operatively connected to the main support means includes, longitudinally extending side grooves formed on the buccal and lingual sides of the center section, and side buttresses are positioned and connected in the respective side grooves. Optionally, a generally U-shaped pontic clip is adjustably positioned in vertically disposed grooves on the center section to adjust the occlusal surface of the main support bar relative the gingiva of the edentulous space.

A portable exercise device for the full and efficient exercise of any group of muscles provides a predetermined and calibrated resistive force established by virtue of friction forces. The exercise device includes, a housing having an integrally formed handle or a receptacle for attaching an accessory connector at one end and an aperture at the end opposite therefrom, a sheave assembly rotatably mounted in the housing having a exercise cord windably retained therearound, a moveable handle fixed to the end of the exercise cord which extends through the aperture in the housing, a braking assembly operatively associated with the sheave to frictionally and uni-directionally retard the rotation of the sheave assembly when the exercise cord is forceably unwound from about the sheave assembly, an adjustment dial for adjusting the friction forces acting against the rotation of the sheave assembly, and a spring operative associated with the sheave assembly rotates the same during operation of the portable exercise device to normally rewind the exercise cord thereabout.

An apparatus for making and method for forming a dental prosthesis in situ in an edentulouos space defined either adjacent to two existing teeth or between a fixed tooth and a second tooth posterially positioned with respect to the first tooth, and lightly touching the associated gum surface, utilizes a bridge bar assembly having at least one shaped connecting member to be adjustably mounted and connected in the drilled grooves of adjacent teeth, a boss on the bridge bar assembly, and a pontic base adjustably mounted on the boss such that when the bridge bar assembly is in assembled position in the edentulous space for connection to the teeth, the pontic base lightly touches the gum, two spaced mold halves can be placed on the buccal and lingual sides of the edentulous space in which the bridge bar assembly is mounted, (or alternatively, two mold halves with predetermined holes to receive each end of the bridge bar and to permit retention and packing of plastic or pontic forming material), the pontic base can be adjusted relative the associated gum surface to fix the connecting member for the bridge bar assembly relative the drilled section of the teeth, and the edentulous space between the mold halves can be filled with a pontic forming material to form the pontic surrounding the boss on the bridge bar assembly; making the pontic forming material catalytically or chemically set; removing the mold halves; removing the assembly and polishing the sides and undersurface of the pontic or pontics; partially filling the grooves with a filler material; cementing the connecting member in the drilled grooves of the teeth to secure the pontic or pontics in the edentulous space; and applying a cosmetic veneer to the formed pontic or pontics.
