Brief summary

Compare ISQ values of implants placed in antral area in native bone vs regenerated bone with a follow-up at 3 months to compare values changes.

Detailed description

The stability of dental implants is influenced by the type of bone in which the implant is placed. Native bone tends to provide better initial stability due to its density and quality, while regenerated bone, it is logical to think that it may present less stability due to the quality of the generated bone and the presence of defects in the treated area. In this study it has been observed that after 3 months more stability is observed in the antral area, measured in ISQ resonance frequency in implants on regenerated bone, which surprises us and this result is explained in detail in said study.

Design outcomes

Primary

Measure	Time frame	Description
Resonance frequency analysis (ISQ) measurements	3 months	The day of surgery, data were collected by vestibular and palatal, in addition, the mean of both measurements was taken and ISQ data were collected vertically to complete all the information. After 3 months of implant placement we recorded the same measurements and compared them in native and regenerated bone.

Secondary

Measure	Time frame	Description
Insertion torque measurements	During implant placement	Analysis of the insertion torque values measured in Newtons per centimeter (Ncm) and comparing the results of both groups.
Changes in the marginal bone	3 months	Analysis of the changes in the marginal bone three months after implant placement
