Abstract : Dental implant placement in posterior maxilla with deficient bone height is a challenge as it de-mands grafting the sub-sinus bone to accommodate dental implant not less than 10 mm.The trauma and healing time associated with any grafting procedure and the chance of getting lesser primary stability in poor quality bone of maxilla may demand delayed loading of implants. Here we do a comparison between a minimally inva-sive sinus lift with grafting protocols to place implants of 10 mm length and placement of short and wide im-plants of 7mm height without any augmentation procedures .20 sub sinus edentulous areas with bone height more than 5mm but less than 10mm in single edentulous span guarded by natural teeth were selected for study .10 sites were grafted to accommodate 10 mm (Group A) or longer implants and the other10 sites with short implants (Group B). Results show higher primary stability, less surgical and osseointegrationtime, less trauma and pain for Group B as compared to group A. .Higher primary stability achieved in Group B allowed the im-plants to be early loaded with less procedural cost as there is no biomaterials involved.
