Summary
Severe loss of vertical dimension requires occlusal redesign. New CAD/CAM techniques offer predictable, minimally invasive solutions for restoring jaw relations and function.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Background:
- Severe loss of vertical dimension of occlusion (VDO) can result from chemical, mechanical, or traumatic factors.
- This loss leads to significant esthetic and functional challenges for patients.
- Restoration typically involves complex redesign of occlusal surfaces and prosthetic readjustment of vertical jaw relation.
Observation:
- Traditional methods for restoring VDO can be invasive and require extensive treatment time.
- New Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) techniques offer advanced solutions.
- Long-term provisional restorations produced via CAD/CAM are superior to conventional splint therapy.
Findings:
- CAD/CAM enables the creation of durable, long-term provisional restorations that are permanently inserted.
- These provisional restorations allow patients to adapt to and verify the new occlusal situation.
- The success of treating associated functional disorders can be reliably assessed before final restoration.
Implications:
- CAD/CAM technology facilitates minimally invasive and predictable prosthetic rehabilitation of VDO.
- Permanently inserted provisional restorations allow for functional testing and patient verification.
- Final restorations can retain the precisely adjusted and tested occlusion, enabling individual tooth restoration and reducing overall treatment duration.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
