Influence of Alveolar Bone Drilling and Anatomical Position on Integration

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. The main questions it aims to answer are: * Is absence of alveolar drilling before implant placement gives 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 is 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.
