Aesthetic design of front teeth and shape retaining of alevolar crest are two tough issues for front teeth implant. To retain the shape of alevolar crest, patients should wear the restoration on time after implant surgery so as to prevent atrophy or deformation of alevolar crest. In this case, SHINING 3D Aoralscan, Einscan, and EXOCAD smile design module are used for aesthetic design of front teeth.
Chief Complaint: Front tooth fracture for one week
Diagnosis: Root fracture of tooth 11
Treatment: Extraction # 11 root, and perform real-time implant and resin crown restoration
CBCT is performed before surgery. The results show that the bone mass of tooth #11 is enough, but the thickness of labial bone wall is fewer than 1mm. Therefore the “shield”method is adopted to keep part of the labial tissue so as to prevent the collapse of the labial bone wall.
Prepare the cavity for implant. Place in the Osstem 3.5×15mm TSIII impant. The implant position is accurate, and the implant is stability at early stage.
Keep gingiva tissue for about 1mm thick at labial side, and the “shield”is formed.
Implant Bone Meal
Implant bone meal in the labial“jumping gap”
Try in the healing abutment for further temporary crown preparation
CBCT is performed after surgery to check the location of the implant
Preparation before Intraoral Scan
Scan Body Disinfection/Sterilization
Before intraoral scan, soak the scan body in disinfection fluid for 5 minutes. Then put it in a sterilized vacuum bag. Put the bag in the sterilization cabinet for sterilization at 121℃ and 1.5 atm for 15 minutes.
Scan Body Try-in
Put the sterilized scan body in the patient’s mouth and make sure that it is correctly and completely located. X-ray examination can be used when necessary.
Use Shining3D Aoralscan to obtain the intraoral data of the patient. The scanning process takes about 7 minutes
Face Photo Taking
Take pictures of patient’s face for further smile design and case record.
Use Shining 3D Einscan to collect the face data of the patient.
Import Intraoral Data into Exocad for Design
Import the intraoral order into Exocad, and check the job definition.
CAD Design of Temporary Crown
Use the Exocad smile design module to design the temporary crown restoration of tooth 11 and gingiva contact as required.
CAD design of temporary crown
Design an aesthetically satisfactory restoration based on the face scanned data.
The CAD design of temporary crown restoration is completed.
Import the milling data into milling software for milling. The milling takes about 20 minutes.
Resin crown milling is completed. Stick the base into the resin crown, and an implant temporary crown is formed.
Try the temporary abutment and resin crown in the patient’s mouth. The X-ray examination result indicates correct crown location, suitable abutment, and slightly contacted occlusion. During the period of temporary resin crown, gingiva is remodeled for further restoration.
“Shield”method was applied to retain part of gingiva tissue at labial side and prevent collapse of bone wall.
Smile design makes aesthetic design of front teeth. The combination of SHINING 3D Aoralscan, Einscan, and exocad smile design module enables us to perform aesthetic design based on the patient’s current teeth.
With this digital procedure, patients can wear the temporary restoration on the same day of clinical implant, which is helpful for gingiva remodeling for further restoration.

“Aoralscan is accurate, fast, efficient. With it the doctor can accurately acquire the intraoral information. Satisfactory restoration can be made with the use of equipped professional software for design and milling machine. This digital procedure reduces the chairside operation time and provides patients better experience. Hope it can be widely used.”
