Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Dental implant procedures are performed on two groups of individuals who share the common characteristic of insufficient bone for traditional implantation.

The first group lacks a palatal process, while the second group has a palatal process. Then, compare the initial primary stability of implants in the maxillary bone-type (D4) that were inserted tilted in the palatal process of the maxilla, palatally from the maxillary sinus, with implants inserted axially into the maxillary sinus by using a manual torque wrench.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Increasing the initial primary stability intensity value increases the success rate of implants in general and also allows immediate or early loading procedures to begin. In addition, to avoid complications resulting from inserting implants into the compromised maxillary sinus according to the Summers method. The most important of these is perforation of the mucous membrane lining the maxillary sinus and the possibility of its application in pathological cases of the maxillary sinus, such as chronic maxillary sinusitis and the presence of mucous retention cysts, in which intervention according to the usual Summers method is not indicated.

Despite the previous advantages obtained by this method, there are some disadvantages to the technique of tilting the implants in the palatal direction from the maxillary sinus, which are the limitation of its application to cases with a palatal process of the maxilla in the upper jawbone, which requires performing a three-dimensional radiograph. It was observed in this study and after studying the cross-sections that sufficient thickness for this process was less likely present than in cases of its absence. In addition, prosthetic procedures are generally difficult in tilted implants compared to axial implants.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients must have inadequate bone density in the posterior region of the upper jaw.
* Patients should maintain good oral hygiene.
* The surgical site must be free from infection.
