#debonding

In 2014, Diemah F. Alhekeir, Rana A. Al-Sarhan, and Abdulmohsen F. Al Mashaan collaborated on an interesting study about various possibilities for failure with porcelain veneers. Were the failures the fault of the product, the material, the dentist, or the patient? How and when did the failures occur? All these questions and more were addressed in “Porcelain Laminate Veneer: A Clinical Survey for Evaluation of Failure.”

Establishing the Research Pool

The dentists decided to use 19 women and 10 men in their study of porcelain veneer failures. This group of patients was treated by dental interns, undergraduate dental students, and postgraduate dental students.

Each person in the research pool had to fill out two different questionnaires. The patients also underwent clinical examinations.

The grand total of individual veneers included in the study was 205, and all of them were porcelain laminate veneers from the same maker, attached with either RelyX veneer cement or Variolink Veneer.

Defining Failure

For the purpose of the study, “failure” of the porcelain laminate veneers was defined as fractures or breaks, cracks, or colour changes. The team also considered it a bonding failure if the veneers loosened or separated from the teeth.

Discovering the Problems

In some cases, the discolouration of the veneers was the patient’s responsibility. Poor oral hygiene is usually a factor when this occurs. Also, consuming a lot of tea, coffee, or other dark-coloured or highly pigmented drinks is proven to stain teeth.

About 10 percent of the patients had debonding, which means that the veneer detached partly or completely from the tooth. The study revealed that this was primarily caused by the lack of skill on the part of the dental students. Some inexperience is to be expected with interns and young students; however, a much higher level of care and expertise will be provided if you seek assistance from an experienced dentist in Singapore.

Some wear and tear on the veneers resulted from the patients biting their nails or chewing on pens. Students who suffer from consistent teeth grinding or jaw-clenching also experienced a bit more tooth sensitivity than others— an issue which can be partly resolved with the use of composites with acid-etched temporary restorations.

Rating the Patients’ Satisfaction

Overall, about 35 percent of the patients experienced some level of veneer failure, particularly in the area of altered colouration. Still, the satisfaction levels among the patients were high, coming in at 82.8 percent. The flaws encountered during the study were mostly tiny problems, perceptible to a trained eye but not very noticeable to the average viewer. When patients are guided through the process by an experienced dentist in Singapore, the satisfaction levels and success rates are notably higher.
