Sample Case For All-On-4 Implant Placement 2

First Time In Vietnam

‘All-On-4’ Solution With Advanced Surgical Guide

Exclusively At Dr Hung & Associates Dental Center

Mrs T.T.H, 55 years old, has lost all her teeth in the lower arch and had been using removable denture for the past 10 years. However, since the unfit denture resulted in discomfort and poor aesthetics, she came to us to look for another solution.

After making careful analysis of the patient’s case, we decided to co-operate with associated dental specialists from the US to perform the ‘All-On-4’ solution with advanced surgical guides. This is the most advanced system which has never been implemented in Vietnam before.
All-On-4 is a technique in which only 4 implants are required to be placed on one complete edentulous arch, and then a restoration will be placed on these implants. This technique is optimal for cases where there is severe bone deficiency in posterior teeth (to the side of the molars), does not require bone grafting and is more economical for patients.

sample case 3

Our dental surgeons, prosthodontists and dental technicians at Dr. Hung & Associates Dental Center had been working online with the associate dental specialists in the US to design the surgical guides including 3 guides, which ensured the procedure was performed speedy and accurately. Right after the surgery, patient was applied immediate temporary restoration on implant. At the moment, Mrs. T.T.H is very satisfied with her new teeth.

Following is the complete procedure of the ‘All-On-4’ surgery with surgical guides performed at Dr Hung & Associates Dental Center:

Before the surgery

– Physical examination.
Patient: T.T.H, 55 years old
History:
+ Upper arch: partial removable denture, for 5 years.
+ Lower arch: complete removable denture, for 5 years.
Diagnosis: lower arch’s denture was loose and unstable due to Residual ridge resorption

  • After performing physical examination and basing on the patient’s case, the suggested treatment was an ‘All-On-4’ with surgical guides (place 4 implants in these following teeth: 32, 35, 42, 45 and apply immediate temporary on implant).
    – Take CTCB with Denture
    – Using data from the CT Cone Beam and Nobel Clinician software to develop the treatment plan.
    However, our teams noticed that aveolar ridge at teeth position 32, 35, 42, 45 was sharp, small and unlevelled.
    Therefore, we decided to whittle the Aveolar ridge of the lower arch to expand the diameter of implants and to facilitate restoration
    Working online with dental specialists in the US, we agreed on the treatment plan and the design of surgical guides.

  • After discussions, we decided that surgical guides include 3 guides:
    – The first guide simulated the patient’s denture, fitted her upper arch and was responsible for determinding positions needed to be whittled.
    – The second guide was to check the jawbone ridge after whittled , in order to ensure the arch was flattened and facilitated to place the implants.
    – The third guide indicated the positions of implants. Provisional restoration on implants was designed by CAD/CAM system to apply immediately after implantation.
    Transfer the treatment plan and necessary information to the Laboratory to produce the surgical guides and Provisional restoration on implants
    Final discussion among surgeons about the surgery.

    During the surgery
