Chipped and missing teeth are one of the common oral diseases with many causes, such as congenital absence, dental caries, trauma, periodontal disease, etc., which seriously affects the health and aesthetics of teeth. Restorative dentistry is an important discipline in dentistry. With the advancement of science and technology, restorative dentistry techniques are constantly being developed and perfected, and more and more restorative materials and methods are being researched to provide more choices for patients.


So, what can Ucometry's high-precision measurement technology bring to the development of restorative dentistry?


一、Restorative Dentistry


Patients with missing teeth need to choose dental restoration techniques according to the specific missing condition, which is generally categorized into two major categories: missing teeth and missing teeth.


The dental defects generally refer to abnormalities in the shape and structure of the teeth, affecting the aesthetics and occlusal problems, and the restoration methods for the dental defects are generally fillings, inlays, veneers, etc. The restoration methods for the dental defects are generally fillings, inlays, veneers, etc.

Missing teeth generally refers to a large number of maxillary and mandibular teeth or all of them are missing, which seriously affects the aesthetics, chewing, language pronunciation and other issues.

Dentures, commonly known as "dentures", are used to repair missing teeth and are generally made of different materials such as plastic, porcelain and metal. Dentures can be broadly categorized into two types: removable dentures and fixed dentures.


Denture repair technology is one of the common dental restoration technology, which is mainly divided into movable denture repair, fixed denture repair and dental implant repair.


Fixed Denture Repair: If the teeth are defective but not yet missing, you can do fixed denture repair on the surface of the teeth, i.e. common porcelain teeth; if the teeth are already missing, you can choose to install a fixed denture to repair.

Activity Denture Repair: Activity Denture Repair restorations can be freely removed and worn, usually the amount of teeth is relatively small or the amount of missing teeth more patients will choose activity denture repair, in order to ensure that the basic chewing and eating function and aesthetics.






  • Dental implant restoration: Dental implants are mainly composed of two main parts: the implant and the denture. The implant, also known as an artificial tooth root, replaces the naturally growing tooth root and is implanted into the alveolar bone. Implants are made of titanium alloy or other biocompatible materials with good biocompatibility and osseointegration ability. Implants have a high retention force and can withstand high chewing forces. They also mimic the biomechanical properties of natural tooth roots and help maintain the health of the alveolar bone. However, implant surgery is relatively expensive and has certain financial requirements for patients. If the patient's crown and root have been completely lost, the implant can be implanted in the lost tooth bed, and then a crown can be made on top of the implant for dental implant restoration.



二、What is affected by surface roughness and microscopic 3D morphology in the field of dental restoration?


1. Bacterial adhesion:


The surface roughness of denture and implant has an effect on the adhesion of bacteria and fungi such as Streptococcus pyogenes, Candida albicans, Actinobacillus viscosus, Pseudomonas albicans and so on. The larger the surface roughness, the stronger the adhesion of bacteria and fungi, which can easily cause orthodontist to suffer from stomatitis and other oral diseases. Therefore, it is necessary to measure the surface roughness of denture and implant to control the size of surface roughness and reduce the adhesion of bacteria and fungi.



2. Dental calculus:
The surface roughness of the denture is a key factor in the formation of denture calculus. The rougher the surface of the denture, the stronger the adhesion of plaque. Denture calculus is caused by the calcification of plaque, which adheres to the same part of the denture for a long period of time, leading to the formation of denture calculus. Therefore, the surface roughness of the denture needs to be measured and controlled, and the patient needs to clean the denture regularly to minimize the formation of calculus.

3. Pigmentation:
Denture pigmentation is related to many factors, such as dietary habits, type of denture cleanser, denture cleaning habits, material properties of the denture itself, manufacturing process of the denture, and so on. Relevant research shows that most of the pigment will be deposited on the plaque of denture, the surface roughness of denture is positively correlated with the pigmentation, the larger the surface roughness of denture, the more pigmentation. Therefore, it is necessary to measure and control the surface roughness of denture in order to reduce the pigmentation produced during the use of denture and enhance the color stability of denture.

4. Frictional abrasion of the oral mucosa:
The greater the surface roughness of the denture, the easier it is to stimulate the mucous membrane inside the mouth, the mucous membrane's resistance is reduced, which causes the attachment and deposition of plaque, triggering oral diseases as well as pigmentation, affecting the aesthetics. At the same time, it will also reduce the corrosion resistance of denture, affecting the service life of denture.

5. Soft tissue deposition attachment：
Relevant studies have shown that the smaller the surface roughness of the implant, the stronger the adhesion and proliferation of epithelial cells and fibroblasts, which is more conducive to the healing of the soft tissues, so it is necessary to measure the surface roughness of the implant and to improve the implant material and process.

6. Osteoblast proliferation and differentiation:：
Studies have shown that implant surface roughness and surface micromorphology affect the interface reaction between osteoblasts and implants, which in turn affects osteoblast proliferation, differentiation, etc. Therefore, measuring and controlling implant surface roughness and microscopic 3D morphology is necessary.


三、Dental restorative material testing case study by Atometrics


Recently, Atometrics AM-7000 series white light interferometer has been successfully installed and activated in a QS World University ranked top 50 dental school, which mainly uses it to measure the three-dimensional contour of the implant and the surface roughness of the denture for the research of teachers and students on the dental restoration materials and techniques. Below are some of the test results:

  • Implant contour measurement results:


  • 义齿表面粗糙度测量效果：
