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

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Tilted implants
The tilted implants are inserted palatally into the maxillary sinus
Tilted insertion of implants
Using osteotomes, implants are inserted and tilted from 30° to 45° into the palatal direction from the maxillary sinus.
Straight implants
The implants inserted into the maxillary sinus in an axial direction
Straight insertion of implants
The implants are inserted in an axial direction into the maxillary sinus according to Summers' traditional technique.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients should maintain good oral hygiene.
* The surgical site must be free from infection.
* There should be no contraindications for oral surgery.
For the first group:
\- Patients in the first group must have a palatal process of the maxillary bone determined by radiographic examination.
Exclusion Criteria
* Patients with systemic diseases that impair metabolism or healing at the surgical site.
* Patients with contraindications for surgery, including cardiovascular disorders, blood clotting disorders, anticoagulant use, or uncontrolled diabetes.
