Angulated Abutment is an innovative component designed to adjust access hole position, prosthetic screw angulation and improve cosmetics. Before the development of Angled Abutments, if screws and access holes were positioned jutting through the labial aspect of an anterior tooth, there were basically three options:
1. The double casting technique.
2. Unsightly patch marks which closed the access holes after final insertion.
3. The combination of implant supported posts securing a crown and bridge type prosthesis.

Factors to Consider in Dental Implant Treatment
1. How does the patient feel about surgery?
2. Is the patient prepared to pay the costs involved in implant theraphy?
3. Does the patient have sufficient bone to place dental implants? Bone grafting may be required and this could be a barrier to treatment.
4. If bone grafting is required, is the patient prepared to accept this?
5. Is the patient prepared to accept the burden of maintenance associated with implant retained prosthesis?
Implant Analog for Impression
Tools for titanium machining are used for drilling of titanium abutment. The fixture must be well fixed and correct RPM must also be checked before drilling. There must be adequate cooling so that overheating of abutments is prevented.
Titanium Implant Abutment Component
Torque wrench was used to to achieve the desired dental implant bone contact and avoid too much compression on the bone that may lead to necrosis of the implant bed.
Implant was placed mesial to tooth number 22 (FDI Two-Digit Notation).
Following dental implant surgical sequences and protocols, drilling should follow the desired RPM with copious irrigation preferably with an NSS refrigerated the night before surgery.
Drilling Procedure
A cement type prosthesis is recommended in most dental implant cases. The said type of prosthesis has a simple procedure with lesser number of components and most prosthetic complications which could develop later can be resolved by recementation. Impression taking and correct passive fit can be obtained much easier. There is also a study that cement buffer biting force.
Dental Implant body is installed with the recommended insertion torque. Appropriate insertion torque is needed to avoid too much compression of the bone. Excessive compression on the bone blocks blood supply and may lead to necrosis of the implant bed.
Dental Implant is being inserted mesial to 14 - FDI Two-Digit Notation, upper right first premolar.
These are the Guidelines in Treatment of Aesthetic Implant Cases, according to Dr. Sherwin Villareal, Resident Oral Implantology, Ashman Department of Periodontology and Implant Dentistry, New York University, College of Dentistry.
1. Pre-surgical planning
2. Site development
3. 3-D Implant positioning
4. Soft tissue management
5. Provisionalization
6. Prosthetic management
Dental Implant placed mesial to 14 - FDI Two-Digit Notation, upper right first premolar.
Bone quality for the 3rd implant is assessed under the raised full thickness flap. Drilling should follow the same desired RPM ang copious irrigation preferably with an NSS refrigerated the night before the surgery.

According to Dr. Sherwin Villareal – NYU, “The establishment of optimum and predictable esthetics is one of the most important and challenging aspects of rehabilitaion with dental implants.” Esthetic rehabilitation has to be predictable implying reproducibility and stability of the outcome in both short and long term. Achieving these characteristics depends on the interactions between multiple valuables namely biological, surgical, prosthetic and implant design.
