Dental implants are the teeth replacement option of choice for most of the developed world today. This particular dental prosthetic offers a broad range of benefits and well accepted in the dental community, even for the patients. Dental implants provide a predictable, efficient, and reliable means for tooth replacements.
Additionally, dental implants offer completely and partially edentulous patients the function and aesthetics they had with natural dentition. It enables patients to regain normal masticatory function, aesthetics, speech, smile, and deglutition. Many patients have reported having their quality of life improved after placement of implants to replace the loss of natural teeth. Even in senior folks, they are able to masticate and speak better. Improved function and aesthetics have brought about a better lifestyle for those people.
Edentulous patients gain a feeling of higher self-esteem and well-being. In patients with craniomaxillofacial defects, implants can be used to replace ears, noses, eyes, and other maxillofacial defects. Moreover, congenital, traumatic, and developmental oral defects can be treated with implants.
However, there are cases where the implant fail in the oral cavity after placement is done. It all boils down to how well the implant piece fuses with the bone.
Osseointegration is a good indication of the clinical success of titanium implants referring to the direct anchorage of such implants to the surrounding host bone. In spite of the high success rate of endosseous dental implants, they do fail. A lack of initial stability, surgical trauma, and infection seem to be the most important causes of early implant failure. Failures associated with overload comprise of cases in which the functional load applied to the implants exceeds the capability of the bone to withstand it. Failures that occur between abutment connection and delivery of the prosthesis are most likely caused by unfavorable loads. Systemic problems such as an uncontrolled diabetes, the intake of biphosphonates can affect the osseointegration.
There are some ways the implant can fail. Biological failures, which can be further divided according to chronological criteria into “early failures.”
(a) inability to achieve osseointegration that might indicate an interference with the initial bone healing process and “late failures” (inability to preserve the achieved osseointegration);
(b) mechanical failures, which include fracture of implants and related superstructures;
(c) iatrogenic failures, where osseointegration is achieved
but due to the wrong alignment of the implant, it is excluded from being used as part of the Anchorage unit – removal of implants due to a violation of the adjacent anatomical structures such as the inferior the alveolar nerve.
This is why dentists are quite particular in their case selection for implant candidates. Adequate provision of implant primary stability is imperative to attain successful osseointegration. The local bone density has a significant influence on such stability, which is an important determinant of implant success.
Hence, it is necessary for a proper consult with your local dentist to how he or she will carry out the procedure. The dental practitioner will check whether the condition of your jaw and the alveolar process is suited for such a procedure. If not enough bone present, you might need to go through a bone grafting procedure to increase the height of available bone to support the dental prosthesis.
