CAD CAM in Dental Implants

In recent years, implant technique is widely used for replacing a lost dentition inside the oral cavity. Osseointregrated implant system has been introduced and used in many countries. A lot of company offers various implant system in the market worldwide. Different fabrication style of implant are now available but with the advancement of technologies, like the development of different system supported by computer, CAD-CAM is now used in almost all dental lab field.

2. Immediate pressure for implant restoration.
3. Fabrication of custom abutment.

Demineralized Dentin Matrix on Alveolar Bone with Implant

One study in Korea, describes the use of autogenous demineralized dentin matrix as material for repair of various alveolar bone defect. According to the study, several cases of tooth and alveolar bone loss were treated with titanium implants with demineralized dentin matrix as bone grafts.

Wounds were classified:
1. Guided Bone Regeneration with demineralized dentin matrix powder.
2. One or two wall repair with root form.
3. Volume or anatomic defect repair with root on.
4. Socket preservation.

Protocols in Implant Dentistry

With the increasing number of implant pratitioners, the dental laboratories need to be ready to support the demand for implant supported dentures. There are requirements needed in fabricating both fixed and removable dentures. Both dentists and dental technicians should have a common understanding of the techniques and procedures involved. Protocols for both dental clinics and dental laboratories should be established and observed as they work together on implant cases.

Implant System in Anterior Esthetics

Dental Implant therapy has been a predictable treatment modality in long term studies. Nevertheless, the predictability of anterior dental implant esthetics has always been a challenge for the long term results.

Since the alveolar bone around implant platform area constantly shows bone resorption of approximately 1.5 mm in depth and 1.4 mm in depth after function, the recession of gingiva around the implant occurs.

It is possible that we can maintain the alvoelar bone. There are differences among implant systems, regarding bone resorption. Implant designs cause different degrees of bone resorption. Implant and abutment design create differences in anterior esthetics.

Occlusal Schemes for Dental Implant Treatment

Standards for different type of dental implant treatment:
1. When making a fully bone anchored denture, use a mutually protected occlusion to obtain posterior disclusion.
2. When making a overdenture, used a balanced occlusion. The anterior denture teeth are supported by overdenture attachments and the posterior denture teeth are supported by tissues, some molar disclusion is possible to function as a modified mutually protected occlusion.
3. When making a freestanding fixed partial denture for the anterior region including replacement of a canine, use a group function occlusion. During lateral movements, horizontal loads are shared between the natural teeth and the denture.
4. When making a freestanding fixed partial denture for posterior teeth with natural anterior teeth present, use a mutually protected occlusion with posterior disclusion.

Implant Supported Crown

Implant supported crown is a good replacement for a missing single tooth.

Dental Implant supported crowns have the following advantages:

• It looks, feels and performs similar to natural dentition.
• Sound adjacent teeth are not compromised to support a dental bridge.
• It preserves the bone.
• It prevents bone collapse and recession.
• Oral health care is almost same as natural tooth.
• It restores esthetics resulting to good self confidence.

Dental implants will maintain the surrounding bone and soft tissue.
