A New Technique for Controlled Bone Augmentation: The Sonic Weld Device

The placement of implants can be made complicated by defects and degenerative changes in the jaws caused by infection and inflammation. 

For the past 30 years, the field of periodontics has been seeking a device or template to guide bone growth during the healing process. The use of membranes, resembling dressings or filters, addresses this purpose, yet multiple problems are encountered with their placement. Recently, a German company has been offering a device for the preparation of a template for controlled bone augmentation.

A shell (template) composed of lactic acid, a synthetic substance that breaks down in the body following healing, is formed by an ultrasonic device which enables the dentist to control and shape the bone augmentation. The Moria Specialist Clinic in Haifa has been implementing this technique with promising results.

Controlled Bone Grafting Using the SonicWeld Technique

 

Have you lost a tooth?

The loss of one or more teeth is accompanied by bone loss and changes in the general contour of the teeth. Bone volume decreases causing the supported teeth to lose stability.

Need an Implant?

Great! But first the lost bone volume must be reconstructed. Therefore bone must be added/implanted in sufficient quantity and volume so as to incorporate the dental implants.

So how do you build new bone? 

Building bone, or bone augmentation, can be accomplished in several ways. For example, bone can be taken from various other locations in the oral cavity and implanted in the specific site lacking bone. This technique, however, is aggressive and complicated: moreover, it usually requires an additional surgical procedure to remove the screws used to secure the new bone in place. 

Is there another way? 

Yes, with the aid of SonicWeld, which allows the dentist to augment bone and restore the missing bone topography in a controlled way, by means of the ultrasonic device and resorbable pins and membranes. 

The membranes and pins used in the SonicWeld technique are composed of lactic acid (Poly-D-L-lactic acid or PDLLA), which is resorbed by normal body metabolism without leaving a residue. The degradation process is gradual and is completed only after consolidation of the new bone formed in the implantation site.

The lactic acid polymer of PDLLA - a neutral body substance - is broken down into water and CO2 as part of the normal body metabolism.

An important advantage of the material is its exceptional dimensional stability, allowing the dentist to perform bone augmentation with precision in the dimensions of height and volume, which then remain unchanged during the consolidation phase. 

A Solution That Melts into a Permanent Smile

The SonicWeld technique also offers the option of pre-shaped membranes that enable the dentist to reconstruct the structural anatomy of the bone and gums of the anterior teeth.

The ultrasonic technique and resorbable materials of SonicWeld are in much demand due to their great success in the process of bone augmentation. The technique is ideally suited for this, as it assures the creation of the conditions required for reconstructing lost bone prior to implant placement.  Treatment with the SonicWeld technique has no associated risks or complications and is a worthwhile investment for the long-term.
