A dental implant is a structure made of alloplastic materials embedded in the oral tissues under the mucosa and/or periosteum or through the bone to provide retention and support for a fixed or removable dental prosthesis (1). Implantology is the second oldest dental profession; and exodontia (oral surgery) is the oldest. Dental implants became a scientific cornerstone after Dr. Branemark's accidental invention that helped evolve the concept of osseointegration, which is the direct, rigid attachment of an implant to bone without any intervening tissue between the two implants (2). Correct knowledge of anatomical features and their variations before implant placement is necessary to ensure a precise surgical procedure and protect the patient from iatrogenic complications (3). A precise assessment of individual anatomical factors such as the position of the mandibular canal, maxillary sinus, width of the cortical plates, existing bone density, etc. is very important in the correct selection of implants and planning the most suitable position of the implant in the existing clinical condition. Important anatomical structures in the maxilla are the floor of the nose, the nasopalatine canal anteriorly and the maxillary sinus posteriorly. Iatrogenic sinus perforation is a common complication. This problem can be solved by choosing short implants and sinus lift and bone augmentation (4). The most important anatomical consideration when placing an implant in the mandibular arch is the location of the inferior alveolar canal containing the inferior alveolar nerve and artery. Injury to these vital structures during implant placement can cause pain, altered sensation, excessive bleeding, etc. Therefore, it is important to determine the location as well as the configuration of the mandibular canal before implant placement (5). The aim of the work is to investigate, present and describe the satisfaction of patients after the installation of dental implants and the connection of satisfaction with gender, age, chronic diseases and possible complications. The work contributes to science and the profession by showing the causes of patient satisfaction in relation to gender, age, diseases and complications. The results of the research point to interventions that could potentially reduce the causes that lead to dissatisfaction and reduce the complications that may occur. The paper can serve as a source of data for the preparation of other professional and scientific works.
