About this trial
The goal of this clinical trial is to learn if alveolar bone drilling and anatomical position of an immediately placed dental implant has influence on the primary stability, osseointegration and function. It aims to answer these questions:
* Does absence of alveolar drilling before implant placement give the same result as traditional osteotomy with apical drilling? * Is palatinal root position of implant as succesful as central position?
Researchers will compare crestal bone levels and primary stability of the implant after insertion in the groups. Subjects will be assigned to groups, acoording to clinical situation. Study groups:
1. Dental implants will be placed in the extraction socket with an apical osteotomy. 2. Dental implants will be placed in the extraction socket without performing an osteotomy. 3. Dental implants will be placed in the centre of the extracted maxillary molar socket. 4. Dental implants will be placed into the palatal root socket of the extracted maxillary molar.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
≥ 18 years old.
healthy patients without medical contraindications for dental implantation surgery.
removable and non-molar teeth indicated for extraction in both jaws
healthy soft tissues (bleeding on probing < 20%, plaque index < 25%);

Treatments tested in this trial
dental implant placement
Procedure/SurgeryAfter tooth extraction, dental implant is placed
Dental implant
DeviceSmall sterile titanium screw-type with rough surface placed it into the jawbone - just underneath the gum. The titanium implant will fuse over the bone (also known as osseointegration), forming an anchor for a replacement tooth.

Group D: Palatinal molarExperimental treatment 2 interventions
Trial outcomes
Primary outcomes
1
Implant success
Implant will be considered integrated if implant will meet criteria follwing criteria: •. The implant is in its original position. * There are no persistent complaints. * There is no peri-implant inflammation. * There is no implant loosening. * There is no peri-implant radiolucency.
Time frame
16 weeks after implant placementSecondary outcomes
1
Marginal bone stability after one year post-treatment
Marginal bone loss will be measured in mm on radiographic images, which will be calibrated.Marginal bone loss around the implant was assessed by measuring the distance from the implant-abutment junction to the initial point of bone contact on both the mesial and distal sides, and an average was determined for each implant.
Time frame
1 year after delivery of final crown on an implant2
Implant insertion primary stability
Primary Implant stability was determined using resonance freaquency analyzer (RFA) in both the buccolingual and mesiodistal direction and an average value is noted down. RFA calculates value in terms of ISQ (Implant Stability Quotient) ranging from 0-100. ISQ value was measured for each implant at the baseline
