Influence of residual ridge resorption patterns on fixture placement and tooth position, Part III: Presurgical assessment of ridge augmentation requirements.

Implant diagnostic methods using computed tomography with barium-coated templates have revealed the relationship between the optimal final tooth position and the residual alveolar process or ridge. While information with regard to emergence axis, anatomic limitations, fixture length, buccolingual cantilever, and prediction of the the final prosthetic design is available, presurgical information relating to the reconstruction potential of smile zone deformities remains elusive. The use of a complete provisional wax-up and the modification of a barium-coated template design can provide the implant team with presurgical information regarding the need for augmentation of hard tissue and soft tissue and the volume of tissue needed for reconstruction. This information can assist the implant team in the development of realistic treatment objectives and in more accurately addressing the needs and concerns of the patient during presurgical treatment planning.
