Summary: An implant treatment should be principally and consistently planned in conjunction with a previous peri-implant­ological and following post-implantological prophylaxis. Diagnostic preventive and therapeutic measures have to be tuned to the individual risk and predisposition of the patient in concern: Suitable operative and prosthetic risk management, briefing and monitoring of the patient with regard to suitable oral hygiene and professional dental cleaning at the intervals indicated for the respective patient, if applicable, with increased frequency, are key factors which aim at ensuring a long-term stable dental implant treatment. It is recommend­ed to start NIWOP as preventive workflow long before a planned restorative dental implant in order to establish and customise good hygiene habits on the part of the patient so that an implantation can be performed in an inflammation-free environment.

Introduction

 

The development of biofilm is regarded as the proven root cause for the development of inflammation around teeth and also implants. A consistent compliance with the NIWOP Concept (No Implantology without Periodontology) presented by the Bürmoos Dental Company W&H in coopera­tion with Dr. Karl-Ludwig Ackermann and Prof. Dr. Anton Sculean at the Europerio in Amsterdam 2018 for the very first time ensures that the peri-implantological periodontal setting remains stable in the long term and is maintained post-implantologically by means of implementing a consi­stent after-care concept which is tuned to the requirements of the individual patient.

The fewest patients lose their teeth as a result of traumatic or other suddenly onsetting circumstances. The normal case in practice is results from previous long-term periodontal diseases, be it on the grounds of lacking hygiene, a possible predisposition or accompanied by systemic diseases promoting gingivitis. Is an implantation at all possible in such an unfavourable environment (Fig. 1, 2), or is the later peri-implantitis triggered by the implantation treatment?

Almost half of the implant patients develop a controllable mucositis according to today‘s findings, in over 20 % of the patients a peri-implantitis develops therefrom at a later point in time (Fig. 3, 4, 5, 6) [2]. Despite some promising approaches and intensive research, peri-implantitis at the current point in time is only regarded as insufficiently treatable – and no standard therapy exists yet. Thus the best peri-implantitis is such that does not occur in the first place. It is absurd to imagine that it will be possible to train a patient who has not sufficiently mastered his oral hygiene for over many years to achieve an exemplary oral hygiene setting following an implantation. In the case of other implant patients the systemic risks or motor restrictions resulting from diseases also remain. And as far as other implant patients are concerned, the systemic risks or disease-induced movement restrictions also remain. Care of the implant thus imperatively includes a pre- and post implantologic hygiene protocol.

Pre-implantologic preventive medical care

According to current studies, untreated periodontitis patients face a higher risk of developing a manifest peri-implantitis following an implantation, similar to periodontal patients who underwent an initial treatment, but after that did not take part in further supportive treatment and a recall programme [8, 6]. NIWOP starts off with peri-implantological diagnostics which, besides PSI/PSR (Periodontal Screening Index/Periodontal Screening and Recording), BOP and the determination of pocket depths also includes the investigation of systemic diseases with a special risk. That includes patients suffering from diabetes, rheumatoid arthritis, hyperten­sion, as well as cardiovascular diseases in the case of stroke patients who are suboptimally medicated. On the one hand many studies indicate that periodontitis unfa­vourably influences such systemic condi­tions, and on the other the question arises as to whether these diseases and periodontitis are based on the same pathomechanisms. No matter whether cause or effect, the correlation exists and requires a greater attention in the dental practice. In addition thereto, dangerous habits, such as smoking, should be inquired, positively influenced and reduced in the best possible way via suitable measures, or even gradually reduced (motivational inter­viewing) [4, 7].

With positive paro-diagnostics the NIWOP protocol first of all starts off with an initial periodontal treatment. Via profes­sional cleaning dental calculus and biofilm up into the sulcus are removed, subgingival debridement is performed with sonic or ultrasonic devices furnished with special paro-tips. Depending on the situation fur­ther surgical and regenerative measures are implemented. During the treatment the patient is informed in detail of the ade­quate procedure of domestic hygiene and supplied with the appropriate suitable utensils and also, if necessary, instructed as to how such are to be used – caveat dental cleaning errors (Fig. 7−10).

At this point in time the further follow-up appointments should be tuned to the individual situation and the patient‘s skills in order to be able to intervene at an early point in time or to offer professional support. Professional periodontal follow-up care should also be planned individually in the course of which regularly developing new concrements and biofilm are removed by means of ultrasound, air polishing or with the help of manual instruments.

Processes, instruments and materials

The implant treatment is not planned until a stable periodontal status has been reached (initial situation: Fig. 11−13). The very direct communication of this clearly defined order of sequence may help to additionally motivate the patient to diligently comply with the agreed domestic hygiene and planned recall appointments. This is followed by the largely atraumatic implantation e.g. by means of applying piezo-equipment with specially designed tips for bone and soft-tissue surgery or with high-performance dental surgery equipment featuring special motors with special handpieces for a preparation of the implant bed. In addition thereto the selec­tion of the implant system, the type of prosthetic treatment and its later cleanability should be tuned to the individual patient‘s risk (Fig. 14−16). Special focus should be on the site of emergence of the implant and the implant abutment connection which should be as irritation-free, biocompatible and mechanically stable [3]. The single-sided procedure („one abutment – one time“) reflects the most stable peri-­implant situation [1]. Due to measuring the primary stability by means of ISQ (Implant Stability Quotient), it is possible to prematurely intervene or immediately treat after positioning the implant.

Post-implantologic follow-up treatment

As mentioned it is recommended according to the experts to intervene at an early point in time in the case of an onsetting mucositis in order to prevent a progressive peri-implantitis with accompanying loss of bone from developing in the first place [3]. The patient has to be initially informed of and instructed with regard to the updated and necessary domestic hygiene processes possibly resulting from the new prosthetic treatment. In particular use of interdental brushes should be practised at the dentist‘s surgery from various different angles in order to avoid injuries and to ensure thorough cleaning results. The established paro-recalls ranging between two and four times per year depending on the individual patient‘s risk should be continued after the implant with no alterations in order to support and maintain the inflammation-free status via regular professional dental cleaning appointments and to identify inflammatory developments at an early point in time. In the case of an onsetting mucositis a professional removal of the supra- and subgingival biofilm at close intervals has proven to be a reliable method to successfully prevent a further progression of the inflammation or even peri-implantitis. If, despite all preventive measures, e.g. as a result of lacking hygiene on the part of the patient, peri-­implantitis nevertheless develops, the use of suitable ultrasound equipment, support by means of Er:YAG-Laser, the admini­stration of an antibacterial photodynamic therapy (aPDT), Air Polishing or even the administration of local systemic antibiotics are a promising method of preventing a further progression (Fig. 17) [5].

If such a closed treatment is no longer possible, it is necessary to surgically open the defect to decontaminate it, if appli­cable, via suitable means by hard- and soft-tissue augmentation. In the next step following restoration, the prophylactic recall program should come into play, preferably at close intervals.

„What is known and what you should know.“

  • Parodontology and implantology both represent cross-disciplinary subjects in oral and maxillofacial medicine
  • Epidemiologically seen not only the younger adults (age group: 35–44 years), but also the younger seniors (age group: 65–74 years) suffer by over 50 % from a moderate and/or severe periodontitis.
  • It is forecasted that the number of senior patients will rise dramatically. Despite declining prevalence an increase of periodontal treatment requirements is expected in future (about 2030) [9].
  • Implants will thus be primarily needed for the elderly and/or highly elderly patients, i.e. highly aged patients, and in other words the risk of disease (mucositis and/or peri-implantitis) will rise in a similar dramatic rate.
  • Thus the following applies: Only a periodontal healthy dentition, which is kept „healthy“ by prophylactic and dental care measures ultimately offers excellent general conditions to ensure an unproblematic implant prosthesis
  • Knowledge of a periodontal disease and the flanking co-factors as well as the just-in-time therapy represent the key prerequisites for a successful perio-implant treatment option!
