Am I an implant candidate?
Most of the patients are implant candidates, regardless of their age.
If the lower age limit is represented by bone growth ending (17-18 years), there is no upper age limit. As long as the patient’s general health status is proper and he is “qualified” for a dental extraction, implant surgery doesn’t raise outstanding problems.
There are certain patients with compromised general health (any surgical intervention can endanger their life) and therefore, implant insertion procedure must be performed selectively, with caution and with thorough investigations. Additionally, in their case, conditions and special equipment is needed as well as an experienced surgical team (implantologist, maxillofacial surgeon, anesthesiologist, etc.) and interdisciplinary collaboration (cardiologist, neurologist, diabetologist, hematologist, etc.). Otherwise, risks are high and can compromise treatment, even endangering patient’s life/health.
INFLUENCING FACTORS FOR IMPLANT TREATMENT
Atrophy (resorption) of maxillary bone can temporarily hinder implant/implants insertion.
Maxillary bone represents the “foundation” of dental implants!
It has to be firmly anchored into the bone and its lack or poor quality can raise problems. An implant insertion into insufficient bone leads to compromise by choosing an implant which is too thin (if there is horizontal resorption) or too short (if there is vertical resorption) leading to its loss sooner or later due to an “uncalibrated” relation between the replaced tooth and implant diameter/length.
Bone atrophy (resorption) appears especially when, after tooth extraction or tooth loss, replacing is postponed or when teeth are replaced through traditional means, with bridges or dentures. Beneath the body of bridge (“fake” teeth or intermediary), unstimulated bone is resorbed (melted). Likewise, for wearing mobile dentures, their permanent mobility causes dramatic bone resoprtions in time.
Maxillary bone resorption can be:
- Horizontal – bone narrowing (thinning);
- Vertical – bone shortening.
In both cases, bone additions are necessary which are meant to restore lost bone volume, offering implants a solid foundation. Although there are several bone grafting procedures to correct lost bone mass, situations arise when it is impossible or even too risky to perform surgical addition. In Implantodent clinics we have efficient solutions, specialists and necessary equipment in order to successfully treat any clinical situation.
When posterior teeth (molars) are lost from the upper maxilla, maxillary sinuses, which normally lie above the roots, enlarge their volume, occupying increasingly more of the neighboring bone volume.
When there isn’t sufficient bone left under the sinus (height/width), to avoid implant entering the sinus (which is a cavity filled with air), sinus lifting and sinus augmentation are performed (sinus mucosa is lifted and biomaterials are inserted underneath) to restore necessary bone for implant through regeneration phenomenon.
Smokers – Dental implant treatments for smokers can be performed, but they have to accept the fact that the treatment won’t be a complete success, as in the case of a non-smoker patient.
Periodontopathic patient (patient with periodontal disorders) – periodontal disease has microbes as a determining factor (pathogenic bacteria infection) which accumulate in the absence of a proper oral hygiene. Dental implant insertion in an oral cavity where periodontal outbreaks exist involves increased risks which can lead to implant infection (periimplantitis) and its loss.
Even if experience and equipment recommend Implantodent clinics as being the first choice in dental implant treatment we advise you not to take into account this kind of treatments if you aren’t truly convinced you can change your attitude towards oral hygiene and the way in which you will regularly visit the dentist.
A dental implant is being conceived to last a lifetime in a clean and periodically checked mouth. Otherwise, the treatment satisfaction can be short, becoming a wasted and time consuming investment.
Dental implant candidate
Dental implants represent a successful treatment option for the suitable candidate. For carefully and adequately selected candidates, dental implant treatment success rate exceeds 98% after 5 years and 96% after 10 years, turning this option into an extremely predictable treatment when properly performed, following clear rules and protocols, without compromise. Thorough investigation of the case is vital in this regard due to several factors that could influence success in a long term:
- Inadequate bone volume area;
- Presence of periodontal disease (gingival);
- Improper occlusion (bite);
- Degraded general health status (decompensated disorders);
- Smoking – time and number of cigarettes smoked per day;
- Certain administered medication, especially on the long time (intravenous administered biophosphonates in particular);
- Bone metabolism diseases, collagenases;
- Chronic anticoagulant administering (thinning blood);
- High cholesterol level;
- Low vitamin D level;
- Uncontrolled diabetes;
- Cancer treatments – cytostatic (chemotherapy) or radiotherapy.
Most of these factors won’t hamper with implant insertion but they still can delay/postpone procedure performing until health issues are managed.
For example, patients with insufficient maxillary bone (resorption) in the implanting area require bone addition prior to implant insertion. Once with tooth/teeth loss, the particular place on the maxillary bone starts to degrade because it no longer receives stimuli. Neighboring and antagonist (opposed) teeth start to migrate (move) towards the emptiness left behind by the tooth loss and biting is modified by becoming unbalanced. Dental implant insertion in these conditions would turn treatment into failure.
Oral cavity requires thorough draining prior to implant insertion. It involves a detailed descaling, tooth decay treatment and removal of any acute or chronic oral infection.
Periodontal disease, regardless of the stage, must be treated prior to the implant procedure.
Occlusion (bite) must be carefully evaluated and in need rebalanced as part of the implant procedure.
Dental implant insertion is totally not recommended in extremely few cases.
