When severe gum inflammation is present

- August 06, 2022

The patient is a 59-year-old man.

Due to chronic periodontitis in tooth number 21, immediate implant placement was not possible. Therefore, extraction was performed first, followed by socket preservation after the extraction.

Here is the post-extraction appearance.

The infected tissue inside was meticulously removed, dedicating time to ensure thorough removal.

Subsequently, a resorbable membrane (Xenoguide) was placed on the buccal side, followed by the placement of homogenous bone graft material. The area was then sutured.

Here is a post-operative photo.

Q1. I'm curious about the reason for using a resorbable membrane instead of a non-resorbable membrane.

A1.There isn't much difficulty with resorption, and since the anterior area is also lightly protected with temporary teeth, it doesn't seem necessary to use a non-resorbable membrane.

Q2. When is it possible to place the fixture implant?

A2. Expected to place the implant after approximately 4-5 months.

Q3. Do you believe that using resorbable membranes like GenoGuide in an open membrane technique can maintain exposure for about 5-6 weeks, which is the time needed for the formation of sub-membrane connective tissue?

A3. Since it is maintained by PTFE tape (Ponic), there should be no issues, and from around 3 to 4 weeks, the sub-membrane connective tissue starts to cover the lower part. Additionally, if needed, a minor bone grafting procedure could be considered during implant placement.

I also consider the use of non-resorbable membrane in open membrane technique to be a good method.

There are many variables such as bone defects and the extent of infection, so the surgeon needs to assess the situation and make a judgment accordingly.
