Er,Cr:YSGG Laser and CAD/CAM Technology
Case Presentation of a Minimally Invasive Approach to Full-Mouth Rehabilitation
Mark P. Colonna, DDS • Enrico DiVito, DDS • Greg Wiater
This study discusses the use of an Er,Cr:YSGG laser to prepare the hard tissue for full-mouth rehabilitation with CAD/CAM prostheses. Upon reviewing this study, the reader should:
- Be aware of the procedure involved in minimally invasive tooth preparation using emerging technologies.
- Recognize the role of emerging technologies on the delivery of optimal care.
Recent advances in laser and CAD/CAM technology have opened the doors to both patients and clinicians, offering minimally invasive and timely delivery of acceptable dental restorations, often in “same day” timelines. Application of current bonding methodologies with less-than-ideal remaining tooth structure has allowed practitioners to restore compromised dentition while achieving their final desired position, color, and shape.
There are many significant advantages to restoring dentition with conservative and minimally invasive techniques. These include a reduced need for anesthesia, the absence of postoperative sensitivity, secure bonding to the remaining enamel, reduced flexing stress, the potential for reversal of treatment, and higher treatment acceptance. In such instances, case selection is extremely important. Prior to advising patients of any treatment option, the clinician should perform a thorough medical history evaluation and a clinical examination, including photographs, radiographs, periodontal evaluation, mounted models and patient interview. A comprehensive review of hard and soft tissue structures is also required. In addition, the patient’s craniomandibular status as it applies to TMJ/TMD must be documented to effectively prepare a treatment plan that ultimately leads to harmonious dental/alveolar function. Only following this comprehensive review of the patient’s current condition can the practitioner determine the options available to achieve the final restorative results. The clinician should then select the least invasive modaility to achieve the desired clinical outcome. This article will demonstrate how laser and CAD/CAM technologies may be utilized to create these desired results in a manner that is minimally invasive and in a reduced number of office visits.
By combining two relatively new dental treatment modalities (lasers and CAD/CAM technologies), it was possible to rehabilitate this patient’s dentition and dental health. The authors demonstrated that this restorative case could be completed in fewer office visits without the use of the conventional handpiece, no local anesthetic, and implementing same-day milled ceramic restorations.
