science & practice 11EUROPERIO London 2015–3 June Effective wound healing is a key factor determining the success of a surgical process. Any distur- bances to that process may lead to inflammatoryreactionshindering tissue regeneration, as well as var- ious complications, such as exten- sive scarring that creates func- tional and aesthetic problems. Treating the complications is diffi- cult and contributes to discomfort of a patient. Minimising the risk of compli- cations is crucial particularly in precise periodontological proce- dures, as well as in bone augmen- tations. Proper suturing tech- niques and a careful selection of suture material have a direct im- pact upon correct tissue fixing. Absorbable sutures, particularly braided ones, should not be used for external tissue fixing in the oral cavity. The reason for this is a significantriskofbacterialplaque adhesion, a quick loss of sustain- ing properties resulting from harmful effects of digestive en- zymes, and increased susceptibil- ity to microbes penetrating the woundtogetherwithblood,saliva, and nutritional fluids. So far, it has been recom- mended that external fixing of oral cavity tissues be carried out with the use of non-absorbable, monofilament materials, most of- ten made from nylon, polypropy- lene and polyvinylidene fluoride (PVDF). Their scabrous surface does not permeate liquids and does not yield to enzymatic processes, while bacterial plaque aggregation is minimal. Unfortu- nately, traditional non-absorbable suturing materials are not void of faults. The fibers are not flexible enough and will not adapt to the varying volume of the healing tis- sues. Significant rigidity of poly- mers that are the core of their structure is a characteristic ill- taken by the patients. It causes ir- ritation of the mucous membrane andoftenleadstopainfulerosions, as well as viral-caused lesions. From the clinical point of view, in- voluntary contact between the tongue and the irritable spot is un- favorable to the healing process, as well as to the integration of in- grafted material or transplanted tissues. Currently,itseemsthatthebest suturing material for dressing the wounds within the oral cavity is polytetrafluoroethylene (PTFE). It is a suture having the characteris- tics of a filament, yet at the same time maintaining unprecedented fiberflexibility.PTFEsutureswere introduced many years ago for de- manding cardiosurgical proce- dures,duetotheirhighbiocompat- ibility and unique physical quali- ties. The various available types of PTFE sutures differ mainly in the structureoffiber.Fordentalproce- dures, during which the sutures have only temporary contact with the tissues, the most appropriate suturing material is one based on a smooth, high-density called dPTFE. It is characterized by a de- gree of flexibility, which is a great asset in tissue fixing, irrespective of the changing volume that ac- companies a given healing stage. High bio-compatibility of dPTFE sutures, the softness of fiber, a re- stricted adhesion of bacterial plaque, and minimized microbial penetration into the wound pro- vide for the highest level of secu- rity. The analysis of clinical useful- nessofsutures45cminlengthhas indicated that most complex den- tal procedures require two pack- ages of the suturing material. Longersutures(approx.75cm)are less comfortable to use: suturing with the use of an instrument is more difficult, while the risk of su- ture infection in a restricted oper- ating area is increased. Therefore, it seems that the most appropriate length of sutures for oral cavity dental procedures is approx. 55cm. The suturing material that meets all criteria discussed above is COREFLON (Booth 52e). It is available in sizes ranging from 3-0 to 6-0 and comes together with high-quality needles with modern geometry. A perfect alignment of the needle’s diameter and the di- ameteroftheTeflonfiberresultsin a significantly smaller post-opera- tive bleeding. PTFE sutures are more expensive than other avail- able suturing materials, but con- sidering their unique characteris- tics of reducing complications af- ter expensive, highly-specialised procedures,thisfactorseemstobe of little relevance.
