Avoiding Post-Implant Placement and Long Term Crestal Bone Resorption by Thickening Vertical Soft Tissue
Our patient is a 60-year-old caucasian male that had just finished a large ridge augmentation in the area of #4 and #5. We used the sausage technique for the ridge augmentation and yielded excellent bone volume in this area. However, as we began the 2nd stage implant placement procedure, we noticed, as is frequently seen following a large ridge augmentation, very thin vertical soft tissue over the crest of the bone. We know that inadequate soft tissue thickness will lead to compromised vasculature and transfer of oxygen and nutrients to the bone which can absolutely lead to a loss of crestal bone surrounding the implants.
THE RISK PROFILE
|Intact immune system
|Impaired immune system
|Patient’s esthetic requirements
|Height of smile line
|Thick – “low scalloped”
|Medium – “medium scalloped”
|Thin – “high scalloped”
|Shape of dental crowns
|Infection at implant sight
|Bone height at adjacent tooth site
|≤ 5 mm from contact point
|5.5 – 6.5 mm from contact point
|≥ 7 mm from contact point
|Restorative status of adjacent tooth
|Width of tooth gap
|1 tooth (≥ 7 mm)
|1 tooth (≤ 7 mm)
|2 teeth or more
|Bone anatomy of the alveolar ridge
Note: Bone was augmented prior to this case report due to a severe horizontal defect.
Our goal here is to create increased vertical soft tissue thickness over the crest of the implant site. Following implant placement and placement of the cover screws, we used Geistlich Fibro-Gide® over the implants and then layed it over the crest and buccal aspect. Following the placement of Geistlich Fibro-Gide®, we gently released the full thickness flap so that we can achieve tension-free primary closure over the site.
The soft tissue that will now surround the implant site is thick and healthy due to the use of Geistlich Fibro-Gide® at the time of implant placement. This is a simple technique and only requires a minimal amount of flap release to achieve tension-free primary closure over the site. The results are phenomenal and will be beneficial for the stability of the crestal bone surrounding the implants for years to come.
Thin vertical soft tissue over the implant site following ridge augmentation is one of the key factors which may lead to crestal bone loss around the implants that will be placed.Tamir Wardany, D.D.S.
I find the Mini-Me Periosteal to be my most versatile instrument for all my hard and soft tissue cases. I always have this instrument out on my surgical tray.Tamir Wardany, D.D.S.
Beginning with thin soft tissue, we were able to achieve very thick and healthy vertical soft tissue over the implants, which will improve blood flow to the bone and minimize crestal bone loss in future.Tamir Wardany, D.D.S.
