Risk Factors In the Failure of Dental Implants

The risk factors to be taken into account in the treatment with dental implants are multiple and varied.

The main factors that we can consider patients with the potential risk of a higher percentage of failures in the Osseointegration of dental implants are very smokers, radiotherapy, periodontitis, osteoporosis, and very advanced ages.

We can talk about systemic and/or local factors and, within them, a long list that we detail below.

All these risk factors can be considered in isolation or correlated between, and for this reason, it is very important to make a detailed clinical history of the patient.

More than half a century ago, in 1952 Dr. Brânemark revolutionized the world of modern dentistry with the discovery, study, and development of dental implants.

With the shape of a coiled cone, the world of dentistry has different models, sizes, and brands of dental implants, such as Nobel Bio care, Brânemark, Microdent, Klockner, Astra, and 3I Biomet.

Risk factors in the failure of dental implants

The main risk factors in dental implants are related to periodontal disease, smoking, osteoporosis, inadequate oral hygiene, systemic diseases, radiotherapy and factors related to dental implants. You are going for dental implant visit some experienced dentist like align beauty orthodontics.

The dental implant allows maintaining the alveolar bone structure after the loss of a tooth.

In the surgical phase, the titanium implant is inserted into the alveolar bone through outpatient surgery.

This phase or surgery is performed with local anesthesia and the patient can be fully conscious or if he prefers and by conscious sedation.

After this phase, the Osseointegration period will start, that is, the formation of bone around the implant; this period of time will be approximately six months.

After it, the prosthetic phase in which the prosthesis will be placed on the implant will begin.

Risk factors for the placement of a dental implant

Before the dental implant is placed, certain factors inherent to the surgery and of a personal nature must be considered, which could condition the treatment. These factors are:

Toxic habits: Smoking.

Systemic diseases

Patient’s medication

Bone structure to be rehabilitated.

Dental implants contribute to restoring the aesthetic, masticatory, phonetic and structural functions after the loss of one or more teeth.

The patient, after the placement of the dental implant and its prostheses on implants, should perform annual reviews in order that the treatment will last over time.

At present, many patients enjoy excellent oral health thanks to implants placed more than 25 years ago.

The success of dental implant surgery in Barcelona lies in a correct diagnosis, treatment plan and in the attitude and predisposition of the patient.

Periodontal disease or periodontitis

The periodontal disease in a partially edentulous patient affects dental implants for two reasons: the similarity between the microflora that colonizes the teeth and colonizing implants.

The periodontitis influences the quality of the bone, in bone height and the buccolingual dimension of the bone is very important for the placement of dental implants at the desired location.

The bone height and width are related and are influenced by the reason for tooth loss. The loss of teeth due to untreated periodontitis is preceded by an uncontrollable and considerable loss of bone which frequently leads the implant patient to present a greater loss of bone as well as a narrower bone than the ideal in the placement of dental implants.

It is also argued that the placement of dental implants in patients with untreated periodontitis has a higher probability of non-Osseo integration or failure of dental implants due to the possibility of secondary infection developing around dental implants as a result of bacterial colonization from bags. Periodontal not treated.

For this reason, Prop dental recommends treating periodontitis first before placing dental implants.

The success of implants according to the amount of tobacco in smokers

The stuff is a risk factor for the placement of dental implants. Tobacco affects implant treatment, so there is a higher percentage of implant loss in smokers than in non-smokers.

The failure rate in smoking patients is significantly higher than in non-smoking patients. Several studies confirm that the consumption of tobacco or excessively smokers compromise the initial survival of dental implants.

Although the exact mechanism by which there is an increased risk of non-Osseo integration of dental implants in smoking patients is currently unknown, it seems likely that factors associated with smoking such as systemic vasoconstriction, reduced blood flow, increased platelet aggregation and dysfunction of polymorph nuclear leukocytes negatively intervene in the Osseointegration of dental implants.

Smoking is also associated with higher levels of marginal bone loss and increased inflammation of the soft tissues. For this reason, it is very advisable that the patient quit this habit before starting the treatment with implants, and do not buy it again later.

Osteoporosis

The osteoporosis affects nearly one – third of the population over 60 years, two times more common in women than in men. In itself, osteoporosis is not an absolute contraindication and treatment with implants may or may not be performed, depending on the degree of bone involvement in the area of ​​implant placement, with greater attention in these patients.

Inadequate oral hygiene

Improper oral hygiene causes the patient to have greater swelling of the soft tissue and bone loss, which adversely affect the dental implant treatment.

Systemic diseases

The placement of dental implants should be well studied in patients with systemic diseases that are likely to be aggravated by the intervention. Some of these diseases to consider are diabetes, hiccups, and hyperthyroidism, chronic infectious diseases, heart diseases, coagulation disorders, etc. In each case, the pros and cons of the treatment will be studied individually, and if the disease is under control, treatment with implants can be carried out.

Radiotherapy

Radiation therapy may cause some side effects in the patient, such as xerostomia, microsites and bone radionecrosis. Initially, the treatment with dental implants is contraindicated, but after at least one or two years, and depending on the specific situation of the patient, the implantology treatment can be reconsidered.

Factors related to dental implants

The factors related to dental implants are several, and some of them are related to a lower survival rate of them. The position of the implant, in the upper jaw or mandible, and in the anterior or posterior sector.

The area of ​​bone where the implants are placed, bones type 1 and 4 present a higher percentage of failures. The length of the implant, the shorter ones have more morbidity and implant losses. The surface of the implant, if it is rough or smooth. The presence of keratinized gum around the implant.

There is no impediment to the treatment of implantology in elderly adults unless they have a systemic disease that contraindicates the treatment. The survival of the titanium implant does not seem to be influenced by the older age of the patients.
