Bone Resorption Issues in Reconstructive Implant Dentistry

Bone Structures - Basic Anatomy

The loss of jawbone tissue that is critical for retaining teeth or being able to replace teeth as needed has etiological (causal) factors that can be confusing at times for patients.

This is the result of atraumatic extraction of the lower teeth. Notice the "hole" on the side of the jaw where the nerve exits and supplies sensory innervation for the lower lip. Adequate quantity and quality of bone.

Massive resorption after 30 years of being edentelous (toothless). Note how jawbone loss has extended down to the "hole" where the sensory nerve is. Patient's dentures now press upon the nerve... not able to wear dentures.

All teeth were extracted with in the last five years. Anterior (front) area mutilated by improper tooth extraction. Remaining areas have tremendous amount of available bone for healthy implants.

Twenty five years of resorption. Canine area was mutilated by improper extraction. Adaqate quantity of bone.

Disaster strikes - patient had teeth extracted at 25 years old. In most cases today this is considered malpractice and could border on criminal behavior. If there is any additional resorption it will be impossible for the patient to wear an upper denture.

The upper (maxilla) and lower (mandible) jaw bones are made up of two different types of bone:

Basal Bone, which forms the basic dental skeletal structure. Muscle attachments are on this type of bone
Alveolar Bone, which forms when the teeth evolve and provides the hard tissue structures that support the teeth. It is the quality and integrity of alveolor bone that infuences the long term retention of the tooth structures

Common Disease Factors

Periodontal disease as well as other types of oral lesions can compromise or have injurious effects on the quality of supportive bone structures (alveolar bone) which can be addressed with either immediate periodontic treatment and/or bone grafting.

Bone Resorption as a Developmental Event

Swallowing, chewing and talking but pressure on the teeth. This is transfered to the bone. Bone tissues, as do other cellular structures, require stimulation in order to maintain its shape and overall health.

When teeth are not present the alveolar bone starts to resorb. Loss of teeth (non-diseased) can be due genetic defects, trauma and extractions.

The amount of bone loss after the first year of extractions is 20-30%!

The procedure of choice for preventing or limiting continued loss of aleveolar bone tissue is to replace missing tooth structures with individual implants when possible. Implants act as artificial roots. They stimulate the bone and can prevent additional bone loss.

The use of various types of bridges serve to replace the cosmetic and functional properties of certain tooth structures... but do little to address the issue of continued resorption of the bone tissues being spanned by the bridge (no direct stimulation of aleveolar bone).

Dentures (a popular treatment for replacing teeth) that are ill fitting can increase the rate at which bone is lost. Implant systems specially designed for dentures and partials are often recommended to address the bone resorption that can be extensive with denture use.

Cross section of CT scan with a 3.5mm x 13.0mm Branemark MarkIII implant placed in upper jaw. 50% of the implant would be in the maxillary sinus (not good). The remaining 50% of the implant is not in bone (also not good).	Cross section of CT scan 3.5mm x 13.0mm Branemark Mark III implant. Adequate quantity of bone.	Cross section of CT scan with a 3.5mm x 13.0mm Branemark Mark III implant. Exessive amount of bone in all dimensions.
