Dental implantation is a surgical process of the jaw bone to support a crown, bridge, denture, and facial prosthesis. The basis of modern dental implantations is called osseointegration, it is the direct structural and functional connection between living bone and the surface of a load-bearing implant. Osteointegrated implants have been used to treat various condition ranging from edentulism to head and neck reconstruction. Dental implants are used to facilitate retention of auricular mandibular, maxillary, nasal, and orbital implants, and for bone-anchored hearing aids. The implant fixture is first placed so as to osseointegrate, and then a dental prosthesis is added. A variable amount of healing time is required for osseointegration before a crown, denture, or abutment is placed which will hold a dental prosthesis. Conventional implant practice dictates a delay between tooth extraction and implant placement, dividing the treatment into two differenced steps.
The success or failure of implants depends on the overall health of the patient and also drugs which interfere with bone metabolism, have adverse effect on the osseointegration. The position of implants is determined by the angle of adjoining teeth. The prerequisites for long-term success of osseointegrated dental implants are healthy bone and gingiva. Since both can atrophy after tooth extraction, preprosthesis procedures such as sinus lifts or gingival grafts are sometimes required to recreate bone and gingiva. The final prosthetic can be either fixed or removable. In each case, an abutment is attached to the implant fixture. Where the prosthetic is fixed, the crown, bridge, or denture is fixed to the abutment either with lag screws or with dental cement. Where the prosthesis is removable, a corresponding adapter is placed in the prosthetic so that the two pieces can be secured together.
Over the past few years, due to the advantages of immediate implant placement and its high rates of success in many cases, the procedure is used widely more routinely.
The immediate implant placement, first of all, reduces the number of surgical procedures. This fact is being popular among patients and increases their acceptance and fewer surgical interventions. According to the clinical way, implants in fresh extraction sites can be placed in the same location as the extracted tooth, minimizing the need for angled abutments and facilitating the positioning of the final restoration. Osseointegration is also more favorable when placing implants immediately following an extraction. Width and height of the alveolar bone are preserved. Immediate placement of implants provides better esthetics for the patient.
Basal dental implantology is an advanced implantology system which utilizes the basal–cortical portion of the jaw bones for retention of the dental implants which are uniquely designed to be accommodated in the basal–cortical bone areas. The basal bone (cortical bone) provides excellent quality bone for the retention and functioning of highly advanced implants. Basal implantology is also known as cortical implantology. An advantage of the immediate loading basal dental implant is that prosthesis is fixed within 72 h of implant surgery, saving time and costs considerably. The need for interim dentures/provisionals is totally eliminated, in addition to avoidance of a second surgery for implant exposure in order to fix the abutment over the implant, hence we can say it is minimally invasive & less complicated procedure–in most edentulous situations–make this as the upcoming and viable option for patients.
