What's the difference between osteoblast and osteoplast?

Osteoblast


Definition:

  • (n.) One of the protoplasmic cells which occur in the osteogenetic layer of the periosteum, and from or around which the matrix of the bone is developed; an osteoplast.

Osteoplast


Definition:

  • (n.) An osteoblast.

Example Sentences:

  • (1) Massive osteoplastic bone tumor in hepatocellular carcinoma is very rare.
  • (2) The types of metastasis expansion in the bones were determined radiologically: the most frequent--osteolytic, less frequent--mixed, and the osteoplastic type (prostate cancer, gall-bladder cancer, and pancreas cancer).
  • (3) Biopsy was performed in seven patients harbouring osteolytic and osteoplastic lesions of the cervical (3 cases), thoracic (3 cases) and lumbar spine (1 case).
  • (4) During osteoplastic surgery of the maxillary sinus routinely performed by the author in more than 700 cases since 1973 a piece of bone (the "Bone Lid") including the attached mucosa is cut out of the anterior wall of the maxillary sinus in such a fashion that it serves perfectly to close the opening again as a free graft at the end of the operation.
  • (5) Unpleasant symptoms such as facial neuralgia and discomfort, were reduced to half after osteoplastic reconstruction of the anterior wall of the maxillary sinus.
  • (6) Only complete opening combined with complete reconstruction serves really eradicating the pathology completely as well as full reconstruction of the middle ear and the external canal; this means osteoplastic epitympanotomy.
  • (7) The method of choice for the treatment was the osteoplastic trepanation with a removal of the haematoma.
  • (8) Surgically, we preferred the transethmoidal route and in some cases the lateral osteoplastic approach.
