Why you should avoid basal dental implants?

Basal vs Crestal implants While searching for dental implants you might have come across with the terms crestal or endosseos implants and basal or discoid implants.

The two types differ in

Insertion in the bone: Crestal is inserted at 90 degrees to the jaw bone, no cutting of gum is required minimally invasive. Basal is inserted side wise or parallel to jaw bone, the process is invasive, but once the basal disc implant is lodged it is sturdier.

Crestal implants need bone to grow around the inserted implant to give it sturdiness and stability before it can take load, basal implants can take load of a new abutment and crown immediately.

Total Time taken to complete the implant process : Crestal implant requires more time as the inserted implant needs to be lodged in bone with additional bone formation around it. Basal implants after inserting in the bone can also be loaded with abutment and crown immediately, practiced by many dentists as ‘teeth in a day’

Healing after surgery: Basal implants surgery is invasive hence takes more time to heal, Crestal implants surgery can heal within a week.

What is Basal?

Basal is a type of bone in the jaw in which implant is placed curious minds can see the picture below for more details.

Our view & opinion on Basal Implant technique

Basal Implantology is a relatively new type treatment with new broad indications and almost no limitations. These hard bone supported implants are placed for immediate loading. Even then at Center for Dental Implants & Esthetics we maintain that basal implants should be used as a last resort when no other implant treatment option or ridge augmentation or grafting is possible.

Why do we say this?

Insertion of basal discoid implants is more invasive (deeper surgery) in comparison to the insertion of Crestal implant which is traditional or classical dental implant.As the basal disc like implants are inserted from the from side rather than at 90 degrees to bone as in case of classical Crestal implant, gums are required to be opened up from the bone surface extensively. This can cause delayed healing especially in aged patients, the blood supply from beneath the gum to the bone reduces It is thus not advisable to open the gum extensively just for placement basal implants.

We believe patients should have minimum discomfort with least invasive process.

Research & History

Scientific Literature published in medical journal PubMed about basal-discoid implants is minimal. Also information on follow up of these types of implant is available for a shorter duration. This technique is new and needs longer years of follow up to actually perceive its success or failure.

Carl. E Misch who is considered Godfather of modern Implantology could publish a 5 year long follow up study on 36 patients only that also with a slight modification in the technique. Other case reports which are published are of little clinical significance since they referred to few number of case and are not considered rich and authentic.

Our views are seconded by a report published in 2015 confirmed our view point where a patient reported, fractured basal- implant and its retrieval became the concern for the dentists as a lot amount of bone was lost in retrieving the broken implant.

In the light of the available facts and study reports, we conclude that, Basal implants, though, have some advantages (immediate loading & possibility of dental implant in low bone density, low availability of bone) but there are more known disadvantages like difficult retrieval after a fracture, more swelling and patient discomfort. Which is why indiscriminate use of basal-discoid implants when other treatments are possible should thus be avoided and case for basal implants should be chosen very carefully and only when necessary.
