AB  - At least since the discovery of the Higgs boson at the Large Hadron Collider at CERN, the Higgs sector of the Standard Model of particle physics has become one of the central research areas of high energy physics. Deviations between measurement and theoretical prediction within this sector have the potential to become a window on the quantum field theories describing nature. Besides the increasing precision of measurements, high-precision predictions are required to become sensitive on possible deviations. The focus of this work is on precise predictions of observables within the Higgs sector. On the one hand, studies of Higgs mass calculations within the context of the minimal supersymmetric extension of the Standard Model are presented, which include partial three-loop contributions. Different kinds of calculational methods are introduced, which, when combined, yield a reliable prediction of the light CP-even Higgs mass for in principle arbitrary parameter configurations. Utilizing the results of this work, the relative uncertainty of the predicted mass of the light CP-even Higgs can be reduced below the 1
