The denture supported by osseointegrated implants is connected to abutments by gold screws. If the denture was damaged and required repair, it could be removed by unsrewing the gold screws. If a single implant fixture failed to osseointegrate and was not able to withstand occlusal forces due to soft tissue formation, the denture could be removed to gain surgical access to the fixture site.
The denture could be maintained and supported by the remaining fixtures. At a later time, another fixture could be placed and may require fabrication of new denture. This kind of dental implant system allow retrievability which is convenient for dental implant maintenance. A lot of patients express strong desire for a fixed type denture and the fully bone anchored denture could be the treatment of choice in implant dentistry.

Implant was placed mesial to tooth number 22 (FDI Two-Digit Notation).
Incorporation of dental implants is viable and possibly cost effective treatment modality in partially edentulous patients. The advantages with incorporation of implants are as follows:
- Improved esthetics by the elimination of visible clasp assemblies.
- Ability to change fulcrums in the arch providing more favorable biomechanics.
- Minimizing rotational and lateral forces on direct and indirect abutment teeth.
- Controlled additional vertical support especially significant in partially edentulous patients with distal extensions.
- Provide additional retention and stabilility to the prosthesis by incorporating an attachment mechanism.
- Simplify prosthesis design and base extension.
- Highly predictable treatment.
- Easy to maintain depending on prosthesis design and attachment system.
- Minimize excessive pressur and trauma to soft tissues and supporting ridge with alteration of the biomechanical forces.
In overdentures retained by Locator attachments, the distribution of dental implants had a significant effect on the force measured on the palate of the oral analogue. The measured load was not significantly lower than the eight dental implant design, when the distance between the four dental implants was sixteen or more millimeters, suggesting that the palate of a four dental implant-retained overdenture with a distance of sixteen millimeter or more, does not contribute significantly to the load transfer to underlying hard palate in the in vitro analogue evaluated.
Dental Implant-Retained Maxillary Overdenture
Overdenture prosthetic treatment is an alternative to a fully bone supported and retained dentures. It provides an effective, if not superior method of treatment. Overdentures can be advantageous, both functionally and esthetically for patients with post surgical or congenital defects. If defects exist, esthetics can be improved by increasing or decreasing the amount of denture base material.
Overdenture prosthetic treatment
The use of dental implants in edentulous patients was first developed by Dr. Per Ingvar Branemark and the type of restorative treatment studied and used was the fully bone anchored denture. After implant placement, healing and subsequent denture insertion, the bone reaches a steady state. This is a balance between forces transmitted through the dentures and implants and bone remodelling capabilities.

Treatment planning is the most important factor for successful results and is an integral part of good communication between the periodontist and the prosthodontist.
Black gums and Allergic Inflammation of gums
This really is frequently triggered by low quality alloy. Lesser quality alloys frequently contain non-refined metallic elements which yield toxic substances throughout formulation. These non-refined metallic elements contain lead, cadmium, iron, mercury along with other undesirable elements.

Classification based on the positions of the screw assembly.
Screw assemblies in two adjacent abutments
This method may be used to connect two cast crowns, two roots or a cast crown and a root.
Screw assemblies in the removable section of a combined prosthesis
The fixed part of the prosthesis is cemented in the usual manner and the removable part is then screwed to the fixed component. In this way it is possible to construct a prosthesis on divergent abutments.

Dental screws are used to attach abutments to implants and prostheses to abutments. Screws designed for abutment to implant attachment have different mechanical properties compared to screws used to attach prosthesis to abutment. The following is a general description of dental screws.
Implant Supported Complete Denture is an optimum solution for Completely Edentulous patient. Implant Supported Denture virtually eliminates slipping and movement. Patients will be able to laugh and speak with confidence and eat food with ease.
Dental Implant supported complete denture have the following advantages:
- It increases comfort and stability.
- It restores a secure biting ability.
- Maintains integrity of facial structure.
- It eliminates need for adhesives.
- It improves facial appearance.
- It improves eating.
- Improves speech and confidence in speaking.
Implant Supported Bridge is an optimum solution for multiple missing teeth. Implant supported dental bridge stays secure and strong. It is comfortable, natural and look like natural dentition.
Dental Implant supported bridge have the following advantages:
- It looks, feels and performs similar to natural teeth.
- Sound adjacent teeth are not compromised to support a bridge.
- Preserves sorrounding bone.
- Dental bridge attached securely to dental implants.
- It prevents resorption of bone.
- Recurrent wear around abutment is eliminated.
- Seld esteem of the patient is improved.
Dental Implants will maintain surrounding bone and soft tissue, as well as replace missing teeth.
