A total of 20 patients from the OPD of Kamineni Institute of Dental Sciences, Narketpally, who needed implants in the maxillary posterior region with deficient maxillary ridge
height were selected for the present study [Figure 1].

defect and fixed partial denture in mandibular ridge defect - a case report.
An additional consideration is that when the maxillary ridge
is more atrophic, the upper horizontal osteotomy will be lower (since the distance from the upper osteotomy to the sinus floor must be 6 mm) and less detachment of the mucoperiosteal flap will be required, reducing the overall invasiveness of the surgery.
In 2009, Contar and colleagues  conducted a study of 15 patients with atrophy of the maxillary ridge
who required bone block grafts prior to implant placement.

Maxillary involvement may result in asymmetric maxillary sinuses, expansion of maxillary ridge
, hemifacial hyperplasia, and so forth .

Atwood did an assessment of the maxillary ridge
as it was never done before; it was done by measuring the constant landmarks of the maxilla and then deriving the ratios of anterior and posterior bone resorption.

Xu said that such a product could also be used in periodontal bone repair, mandibular and maxillary ridge
augmentation, reconstruction of frontal sinus and craniofacial skeletal defects, and other stress-bearing orthopedic applications.
A total of twenty patients who needed implants in the maxillary posterior region with deficient maxillary ridge
height were selected.
As the centrals were mobile so extraction of the crowns with removal of gutta-percha was performed and for the maxillary ridge
deficiency an immediate RPD was planned.
