Repossession of a part of the Asset
The·hire vendor, however, may not be’ harsh enough to take possession of the entire asset. He may leave some portion of the asset with the hire-purchaser. In that case; the purchaser should leave’ the proper balance in the account of the asset, representing the present value of the asset stillin hand and write off the balance.

Extraoral Implants
Recognizing the success of implants for oral applications. maxillofacial prosthodontlsts and surgeons have expanded use of titanium fixtures to extraoral application. Extraoral implants are now used to anchor prosthetic

Early Loading
have been efforts to define the minimum time required for osseointegration. Generally accepted integration times • are based on experience and tradition with little experimental data. Researchcontinues to attempt to define ideal minimum integration times. Factors that are likely important in determining what these minimum times should be include: bone quality, implant.material, and surface

Atrophic Maxilla
Initial implant restorative approaches for the fully edentulous maxilla concentrated on implant placement in the anterior- region, simllar to the edentulous mandible. However, the resulting prosthesis was often unsatisfactonry, If adequate space was allowed for proper hygiene,
phonetics and esthetics were severely compromised, If the prosthesis was developed in such a way as to eliminate these,

Atrophic Anterior Mandible
In the atrophic mandible (l.e., less than ‘8 mm of vertical height), the shortest implant may be longer’ than the available bone. Implants may be placed by purposefully perforating the inferior cortex. This’ may decrease the crown-to-root ratio or increase th, risk of “fracture .’ Recent studies have shown that afte. restoration ‘ofthe. atrophic m
Anterior Maxilla Esthetic Zone
In the esthetic zone of the anterior maxilla, successful integration alone is not adequate. The implant must have proper position, angulation, and depth for esthetic restoration. These parameters are prosthodontically determined and communicated to the surgeon by the surgical stent. TIie stent must show the ideal position; labial thickness of porcelain and metal; and locationR
