Today, the clinician is confronted with numerous options at the day of tooth extraction. Recent research provides evidence that while immediate implants are a treatment option for highly selected cases, daily practice requires more flexibility and additional therapeutic options applicable for every day cases. Ridge preservation procedures have been documented in the literature for more than 20 years. Only within the last 5 years has clinical data supported the use of bone substitute materials in conjunction with autogenous grafts or collagen membranes/matrices to counteract remodelling and resorption processes that occur inevitably after tooth extraction and cannot be overcome with immediate implants. Applying ridge preservation procedures reduces these substantial changes in horizontal ridge width and vertical ridge height to only 15-20%. Therefore either early or delayed implant placement after ridge preservation can more often be performed without the need for additional guided bone regenerative procedures, thereby offering a simplified clinical protocol for clinicians and reduced patient morbidity.

Learning Objectives

• To understand morphological changes that occur after tooth extraction
• To know the current clinical evidence on ridge preservation procedures
• To understand benefits when performing ridge preservation procedures compared with comparative treatment modalities
• To understand indications for ridge preservation

Post-extraction resorption of the alveolar bone is closely linked to the resorption of the bundle bone after tooth removal. This resorption can be reduced to a negligible amount when partial extraction therapy (PET) is performed: socket shield, pontic shield and root submergence procedure. The socket shield procedure involves the retention of the facial root fragment together with its periodontal ligament, while the rest of the root is extracted. At the same session or in a delayed procedure, an implant is placed palatal/lingual to the retained root fragment.

PET is a relatively new treatment philosophy, with increasing scientific evidence. It is spreading fast among clinicians because of the excellent and predictable aesthetic results achieved, due to the maintenance of the buccal and interproximal bone.

It can be anticipated that PET will be the first choice of treatment for socket type I, especially for sites with thin biotype, adjacent and multiple implants.

In this lecture, data from the current literature will be confirmed by numerous cases of failed central incisors treated with the socket shield therapy and dental implants. Indications, contraindications, complications and how to manage them will also be discussed.

Learning Objectives

• To understand the biological background of partial extraction therapy
• To understand the indications and contraindications of socket shield therapy
• To recognise misinformation about partial extraction therapy

Despite the successful evolution of implantology in the last fifty years, not all of the clinical problems are completely solved today. One of them is the high risk for adverse aesthetic outcome when implants are placed in the zone of aesthetic priority, and the subsequent trial to surgically improve the results. Many of these problems manifest as mucosal dehiscences after insertion of the prosthetic crown. But the causes of aesthetic failures can originate in all treatment sequences from tooth extraction to final prosthetic restoration.

In the literature of recession coverage, one of the first techniques described to cover mucosal recession around teeth was the envelope technique. The waiving of releasing incisions guaranteed a stable wound environment and made the approach technically insensitive, but at the same time restricted its indication.

The goal of the presentation is to evaluate how far the modern tunnelling techniques differ from the original envelope technique and if an envelope approach around teeth can be applied one by one to cover a mucosal dehiscence around an implant. Knowledge of the differences in the structural anatomy of the peri-implant mucosa and the periodontal tissues gives us new ideas for mucosal envelope approaches. These will be illustrated by clinical cases and explained step by step.

A critical appraisal regarding the technical sensitivity of the different procedures will help the clinicians to choose one or the other approach in order to give the best individual prognosis to each single patient.

Learning Objectives

• To understand how far the modern tunnelling techniques differ from the original envelope technique
• To understand if an envelope approach around teeth can be applied one by one to cover a mucosal dehiscence around an implant
• To gain knowledge of the differences in the structural anatomy of the peri-implant mucosa and the periodontal tissues
• To appreciate how a critical appraisal regarding the technical sensitivity of the different procedures will help to choose the approach that will give the best individual prognosis to each single patient

Diverse clinical advancements together with some relevant technical innovations have led to an increasing popularity of tunnelling flap procedures in plastic periodontal and implant surgery in the recent past. This trend is further promoted by the fact that these techniques have lately been introduced to a considerably expanded range of indications. While originally described for the treatment of gingival recession type defects, tunnelling flap procedures may be successfully applied today in a variety of clinical situations where augmentation of the soft tissues is indicated in the aesthetic zone. Potential clinical scenarios may include surgical thickening of thin buccal gingiva or peri-implant mucosa, alveolar ridge/socket preservation, implant second-stage surgery as well as soft tissue ridge augmentation or pontic site development. In this way, tunnelling flap procedures developed from a technique that was originally merely intended for surgical root coverage into a capacious surgical conception in plastic periodontal and implant surgery.

The aim of this presentation is to provide a comprehensive overview on tunnelling flap procedures, to introduce the successive development of the approach along with underlying ideas on surgical wound healing, and to present contemporary clinical scenarios in step-by-step documentations related to peri-implant soft tissue reconstructions, which aim to provide clinicians with guidance to help them integrate tunnelling flap procedures in their daily clinical routine.

Learning Objectives

• To gain a comprehensive overview on tunnelling flap procedures
• To understand the benefits of using tunnelling flap procedures in clinical situations where augmentation of the soft tissues is indicated in the aesthetic zone
• To appreciate how tunnelling flap procedures can be integrated in the daily clinical routine

Leucocyte- and platelet-rich fibrin (L-PRF), a second generation platelet concentrate and completely different from PRP or PRGF, is an autologous blood derived product, which can be obtained quickly and at low cost.  L-PRF is produced from peripheral blood, which is immediately centrifuged without any anticoagulant.  L-PRF is rich in fibrin, platelets (± 90% of initial blood) and leucocytes (± 70% of initial blood), and can be transformed into strong membranes circa 1 mm in thickness.  L-PRF membranes release large amounts of growth factors for a long period (up to 7 days) and they possess an antibacterial capacity.  

As such L-PRF membranes offer “significant” and “clinically relevant” advantages in several indications including: healing of non-responding wounds, ridge preservation, sinus augmentation, horizontal/vertical bone augmentation and osseointegration.  

The aim of this presentation is to provide basic information on the content of L-PRF and on its clinical benefits in dento-alveolar surgery.  Moreover, the differences between 1st and 2nd generation platelet concentrates, as well as differences between L-, A- and A+ PRF will be discussed. The presentation will give you the support to start to use this new “concept” without further dilemmas!

Learning Objectives

• To understand the differences in platelet concentrates
• To understand the basic steps in the preparation of L-PRF and how it differs from other PC
• To understand the biological background of L-PRF
• To understand the clinical benefits of L-PRF in dento-alveolar surgery
