Due to the fact that the prosthesis constituted the ideal shape of the teeth, it was worth comparing it with the final prosthetic work and assess- ing the details of the whole work process before the pa- tient sits comfortably in the dental chair (Figs. 21–25). If the quality of the work satisfies our expectations, we may proceed to the handing-over stage and perform the functional and aesthetic analysis, both intra- and extraorally. A perfect conclusion to the treatment pro- cess is the receipt of a complete set of OPG X-rays taken before, during and following treatment (Figs. 29–32). contact Dr Tomasz Śmigiel, M.Sc. graduated from Silesian Medical University in 1997. Author of multiple publications for specialist magazines about dentistry and a lecturer at numerous congresses. In 2012 he was certified with the title of a Master of Science in Oral Implantology at the J.W. Goethe- University in Frankfurt/Main, where he conducted research on an innovative system of synthetic telescopes. He is also the co-founder and a board member of Implant Masters Poland, a non-profit association. He can be contacted at tomasz@smigiel.net. Conclusion The performance of prosthetic reconstruction always requires a detailed plan. At present, when planning implantological treatment, the use of advantages that CBCT-based imaging has to offer has become obligatory. As a result of that, one can avoid certain complications that result from im- proper recognition of anatomical conditions. Plan- ning prosthetic restorations based on implants re- quires even more precision than restorations based on own teeth due to the necessity of acquiring pas- sivity in the construction’s adhesion to implants. Due to the fact that patients prefer fixed pros- thetic restorations, the author recommends mak- ing bridges or prosthesis that enable disassembly for maintenance purposes. In such situations, these restorations are based on telescopic or screw- retained abutments._ Work completed in cooperation with Inter-Dent laboratory in Warsaw, Poland.
